具体实施方式Detailed ways
本申请的说明性实施例包括但不限于数据同步方法、系统、介质、程序产品和电子设备。Illustrative embodiments of the present application include, but are not limited to, data synchronization methods, systems, media, program products, and electronic devices.
下面结合附图详细说明本申请实施例提供的技术方案的具体实现过程。The specific implementation process of the technical solution provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
如前所述，目前在某一电子设备和另一电子设备之间进行过数据的同步后，若用户修改了其中一个电子设备中的数据，则两电子设备之间再次进行数据同步时，仍需将全部数据发送给另一个电子设备来完成同步，这种数据同步的过程耗时长、效率低，用户体验较差。例如，手机10中存储有10000条联系人信息，并且该10000条联系人信息已经同步至智能手表20，当用户修改了手机10中的其中一条联系人信息后，手机10再一次向智能手表20同步联系人信息时，仍需要将包含该修改后联系人信息的10000条联系人信息再次发送给智能手表20，如此存在耗时长、效率低的问题。As mentioned above, after data synchronization is currently carried out between an electronic device and another electronic device, if the user modifies the data in one of the electronic devices, the data will still be synchronized between the two electronic devices again. All data needs to be sent to another electronic device to complete the synchronization. This data synchronization process is time-consuming, inefficient, and has a poor user experience. For example, there are 10,000 pieces of contact information stored in the mobile phone 10, and the 10,000 contact information has been synchronized to the smart watch 20. When the user modifies one of the contact information in the mobile phone 10, the mobile phone 10 once again sends the contact information to the smart watch 20. When synchronizing contact information, the 10,000 pieces of contact information containing the modified contact information still need to be sent to the smart watch 20 again, which is time-consuming and low-efficiency.
为了提高电子设备之间数据同步效率，在一些实施例中，可以由手机10记录与其他电子设备之间进行数据同步的日志，并记录手机10在上一次与其他电子设备之间同步数据之后，由于用户的修改、删除、新增等操作而导致发生变化的数据内容，从而在下一次与其他电子设备同步数据时可以仅对有变化的数据进行同步，减少了同步的数据量，进而提高数据同步效率。但是，这种同步数据的方式，需要占用手机10的存储空间来存储与各个电子设备进行同步的日志以及上述有变化的数据，数据存储结构复杂，并且在记录的日志或有变化的数据被清理后，仍需将手机10中存储的全部数据同步至智能手表20，耗时长、效率低，影响用户体验。In order to improve the efficiency of data synchronization between electronic devices, in some embodiments, the mobile phone 10 can record a log of data synchronization with other electronic devices, and record the last time the mobile phone 10 synchronized data with other electronic devices. The data content that has changed due to the user's modification, deletion, addition, etc. operations, so that only the changed data can be synchronized the next time the data is synchronized with other electronic devices, reducing the amount of synchronized data and thus improving data synchronization. efficiency. However, this method of synchronizing data requires occupying the storage space of the mobile phone 10 to store the logs synchronized with various electronic devices and the above-mentioned changed data. The data storage structure is complex, and the recorded logs or changed data are cleared. Afterwards, it is still necessary to synchronize all the data stored in the mobile phone 10 to the smart watch 20, which is time-consuming and inefficient, affecting the user experience.
为了便于描述，在本申请实施例中，同步数据时向外发送数据的电子设备，例如上述手机10，以下可以称之为源电子设备，同步数据时接收源电子设备发来的同步数据的电子设备，可以称为目标电子设备。For the convenience of description, in the embodiment of the present application, the electronic device that sends data to the outside during data synchronization, such as the above-mentioned mobile phone 10, may be referred to as the source electronic device below, and the electronic device that receives the synchronization data sent from the source electronic device during data synchronization. The device can be called the target electronic device.
为了解决上述数据同步过程中耗时长、效率低的问题，本申请实施例提供了一种数据同步方法。具体地，该方法中源电子设备通过对存储的各条数据进行分组，并为每个分组确定一个校验码，该 校验码可以基于分组中的各条数据来确定，分组中的数据的内容不同，则分组的校验码也不同。基于此，目标电子设备从源电子设备中再次同步数据时，目标电子设备只需要获取源电子设备中各分组的校验码，并将获取的源电子设备中各分组的校验码与目标电子设备中已同步的对应分组的校验码进行对比，从而确定出校验码不同的差异分组，即所包括的数据存在差异的分组。进而，目标电子设备可以从源电子设备获取差异分组的数据，完成数据同步。In order to solve the above-mentioned problems of long time consumption and low efficiency in the data synchronization process, embodiments of the present application provide a data synchronization method. Specifically, in this method, the source electronic device groups each piece of stored data and determines a check code for each group. The check code can be determined based on each piece of data in the group. If the content of the data in the group is different, the check code of the group will also be different. Based on this, when the target electronic device synchronizes data again from the source electronic device, the target electronic device only needs to obtain the check codes of each group in the source electronic device, and compare the obtained check codes of each group in the source electronic device with the target electronic device. The check codes of the synchronized corresponding groups in the device are compared to determine the difference groups with different check codes, that is, the groups with different data included. Furthermore, the target electronic device can obtain differentially grouped data from the source electronic device to complete data synchronization.
如此，目标电子设备只需要从源电子设备同步差异分组的数据，可以在减少同步数据的数量、提高同步效率的同时，不会增加源电子设备的额外开销，例如，源电子设备不需要记录电子设备与各个目标电子设备的同步日志，也不需要记录电子设备上一次与各目标电子设备进行同步后，源电子设备中有变化的数据。In this way, the target electronic device only needs to synchronize differentially grouped data from the source electronic device, which can reduce the amount of synchronized data and improve synchronization efficiency without increasing the additional overhead of the source electronic device. For example, the source electronic device does not need to record electronic data. The synchronization log between the device and each target electronic device does not need to record the changed data in the source electronic device after the electronic device was last synchronized with each target electronic device.
可以理解，在一些实施例中，源电子设备对存储的各条数据进行分组，可以是对各条数据进行分组存储，例如为每条数据增加一个分组标识，该分组标识用于指示每条数据的分组，又例如在源电子设备的存储器中设置多个存储区域，每个存储区域中的数据为一个分组等。在另一些实施例中，源电子设备对存储的各条数据进行分组也可以是预设一个分组规则，而不对各条数据进行分组存储，源电子设备在确定某一分组的校验码时，可以先根据该分组规则从各条数据中筛选出该分组的数据，并基于筛选出的数据来确定该分组的校验码。为便于描述，以下以“源电子设备对存储的各条数据进行分组存储”进行介绍。It can be understood that in some embodiments, the source electronic device groups each piece of data stored, and may store each piece of data in groups, for example, adding a grouping identifier to each piece of data, and the grouping identifier is used to indicate each piece of data. Grouping, for example, multiple storage areas are set in the memory of the source electronic device, and the data in each storage area is a group. In other embodiments, the source electronic device may also preset a grouping rule to group each piece of stored data without grouping and storing each piece of data. When the source electronic device determines the check code of a certain group, The data of the group can be filtered out from each piece of data according to the grouping rule, and the check code of the group can be determined based on the filtered data. For the convenience of description, the following introduction is based on "the source electronic device stores each piece of stored data in groups".
可以理解，各分组的校验码可以基于各分组中各条数据的具体内容来确定，用于唯一标识一个分组中存储的数据，分组中存储的数据的内容不同，则分组的校验码不同。例如，在一些实施例中，各分组的校验码可以由分组中的各条数据的消息摘要进行逻辑和/或算术运算来确定，例如由各条数据的消息摘要逐个进行异或运算来确定。假设某一分组中包括三条数据，该三条数据的消息摘要为X1、X2、X3，则该分组的校验码可以由X1与X2进行异或运算的结果再与X3进行异或运算得到。其中异或运算是指，进行运算的两个数据具有相同的二进制数位数，按照二进制数的位数逐位比较，某一位相同则输入数据的该位为0，某一位不同则输出数据的该位为1，例如X1＝0101与X2＝1001的异或运算的结果为1100。需要说明的是，多个数据异或运算的运算结果与各个数据进行运算的顺序无关,从而上述分组的校验码也可以由X1和X3进行异或的运算结果再与X2异或运算得到，还可由X2和X3进行异或的运算结果再与X1异或运算得到。It can be understood that the check code of each group can be determined based on the specific content of each piece of data in each group, and is used to uniquely identify the data stored in a group. If the content of the data stored in the group is different, the check code of the group will be different. . For example, in some embodiments, the check code of each group can be determined by performing logical and/or arithmetic operations on the message digest of each piece of data in the group, for example, by performing an XOR operation on the message digest of each piece of data one by one. . Assume that a certain group includes three pieces of data, and the message digests of the three pieces of data are X1, X2, and X3. Then the check code of the group can be obtained by XORing the result of X1 and The XOR operation means that the two data to be operated have the same number of binary digits, and are compared bit by bit according to the number of binary digits. If a certain bit is the same, the bit of the input data is 0, and if a certain bit is different, the output data This bit is 1. For example, the result of the XOR operation of X1=0101 and X2=1001 is 1100. It should be noted that the result of the XOR operation of multiple data has nothing to do with the order in which each data is operated. Therefore, the check code of the above group can also be obtained by the XOR operation result of X1 and X3 and then XOR operation with X2. It can also be obtained by XORing the result of X2 and X3 and then XORing it with X1.
可以理解，源电子设备在检测到某一个分组中的数据发生变化后，例如源电子设备响应于用户的维护操作(例如新增、删除、修改等)，在该分组中新增、删除或修改一条数据时，可以基于发生变化的数据来更新该分组的校验码，使得该分组的校验码可以与该分组中存储的发生变化后的数据的内容相对应。从而目标电子设备在从源电子设备中同步数据时，可以获取到更新后的校验码并确定出该分组为差异分组，以对该分组的数据进行同步。It can be understood that after the source electronic device detects changes in the data in a certain group, for example, the source electronic device responds to the user's maintenance operations (such as adding, deleting, modifying, etc.), adding, deleting, or modifying data in the group. When a piece of data is received, the check code of the group can be updated based on the changed data, so that the check code of the group can correspond to the content of the changed data stored in the group. Therefore, when the target electronic device synchronizes data from the source electronic device, it can obtain the updated check code and determine that the group is a differential group, so as to synchronize the data of the group.
例如，假设该分组的校验码是由分组中的各条数据的消息摘要逐个进行异或运算来确定的，则源电子设备在检测到对某一条数据的新增或删除操作后，可以将该分组的校验码更新为该条数据的消息摘要与该分组当前的校验码的异或运算结果。又例如，源电子设备在检测到对该分组中的一条数据的修改操作后，可以将该分组的校验码更新为：该条数据修改前的消息摘要、该条数据修改后的消息摘要、该分组当前的校验码逐个进行异或运算的结果。再例如，源电子设备在检测到由于用户修改某一分组中的一条数据，使得该条数据的分组变更为另一分组的情况下，可以将该分组的校验码更新为该条数据修改前的消息摘要与该分组当前的校验码的异或运算结果、将该另一分组的校验码更新为该条数据修改后的消息摘要与该另一分组当前的校验码的异或运算结果。具体将在下文 进行详细介绍，在此不做赘述。For example, assuming that the check code of the group is determined by XORing the message digests of each piece of data in the group one by one, after detecting the addition or deletion of a certain piece of data, the source electronic device can The check code of the group is updated as the result of the XOR operation between the message digest of the data and the current check code of the group. For another example, after detecting a modification operation to a piece of data in the group, the source electronic device can update the check code of the group to: the message digest before the data is modified, the message digest after the data is modified, The result of XOR operation on the current check codes of this group one by one. For another example, when the source electronic device detects that the user modified a piece of data in a certain group, causing the grouping of the piece of data to change to another group, the source electronic device can update the check code of the group to the one before the modification of the piece of data. The XOR operation result of the message digest and the current check code of the group, and the XOR operation of the modified message digest and the current check code of the other group to update the check code of the other group. result. Details will be given below A detailed introduction will not be given here.
可以理解，各条数据的消息摘要(Message Digest，MD)可根据各条数据的具体内容得到，用于唯一标识一条数据，也就是说包括不同具体内容的数据，该数据的消息摘要也不同。例如，在一些实施例中，各条数据的消息摘要可以是利用消息摘要算法，例如MD4算法(由Ronald L.Rivest在1990年设计的消息摘要算法，对于一条数据，得到的消息摘要包括128位的二进制数)、MD5算法(由Rivest在1991年对MD4的改进版本。对于一条数据，得到的消息摘要包括128位的二进制数)、安全散列算法(Secure Hash Algorithm，SHA)算法1(由NIST NSA设计的MD算法，对于一条数据，得到的消息摘要包括160位的二进制数)、SHA224、SHA256、SHA384、SHA512等来计算得到。为便于描述，以下各实施例中以通过MD5算法来得到各条数据的消息摘要为例进行介绍。It can be understood that the message digest (Message Digest, MD) of each piece of data can be obtained according to the specific content of each piece of data, and is used to uniquely identify a piece of data. That is to say, data including different specific contents will have different message digests. For example, in some embodiments, the message digest of each piece of data may use a message digest algorithm, such as the MD4 algorithm (a message digest algorithm designed by Ronald L. Rivest in 1990. For a piece of data, the resulting message digest includes 128 bits binary number), MD5 algorithm (an improved version of MD4 by Rivest in 1991. For a piece of data, the message digest obtained includes a 128-bit binary number), Secure Hash Algorithm (SHA) algorithm 1 (by The MD algorithm designed by NIST NSA, for a piece of data, the message digest obtained includes 160-bit binary number), SHA224, SHA256, SHA384, SHA512, etc. For the convenience of description, the following embodiments take the message digest of each piece of data obtained through the MD5 algorithm as an example.
可以理解，源电子设备和目标电子设备可以是任意电子设备，包括但不限于膝上型计算机、智能电视、智能音箱、平板计算机、服务器、可穿戴设备(例如智能手表、智能手环、智能眼镜等)、头戴式显示器、移动电子邮件设备、便携式游戏机、便携式音乐播放器、阅读器设备等，本申请实施例不做限定。下面以源电子设备为手机10，目标电子设备为智能手表20为例进行介绍。It can be understood that the source electronic device and the target electronic device can be any electronic device, including but not limited to laptop computers, smart TVs, smart speakers, tablet computers, servers, wearable devices (such as smart watches, smart bracelets, smart glasses) etc.), head-mounted displays, mobile email devices, portable game consoles, portable music players, reader devices, etc., the embodiments of this application are not limited. The following introduction takes the source electronic device as the mobile phone 10 and the target electronic device as the smart watch 20 as an example.
具体地，图1A根据本申请的一些实施例，示出了一种手机10对联系人信息进行分组存储的示意图；图1B根据本申请的一些实施例，示出了一种智能手表20首次从手机10同步联系人信息的场景示意图；图2A根据本申请的一些实施例，示出了一种智能手表20非首次从手机10同步联系人信息的场景示意图；图2B根据本申请的一些实施例，示出了一种智能手表20非首次从手机10同步联系人信息的过程示意图。Specifically, FIG. 1A shows a schematic diagram of a mobile phone 10 grouping and storing contact information according to some embodiments of the present application; FIG. 1B shows a smart watch 20 for the first time according to some embodiments of the present application. A schematic diagram of a scenario in which the mobile phone 10 synchronizes contact information; Figure 2A shows a schematic diagram of a scenario in which a smart watch 20 synchronizes contact information from the mobile phone 10 for a non-first time according to some embodiments of the present application; Figure 2B shows a schematic diagram of a scenario in which the smart watch 20 synchronizes contact information from the mobile phone 10 according to some embodiments of the present application; , shows a schematic diagram of a process in which the smart watch 20 synchronizes contact information from the mobile phone 10 for a non-first time.
参考图1A，手机10中存储有10000条联系人信息，手机10可以根据联系人信息中的电话号码的后两位，将该10000条联系人信息分为100组，即分组00组到分组99，再根据每个分组的具体内容为各个分组确定一个校验码，例如通过将一个分组中的各条联系人信息的信息摘要进行异或运算来确定该分组的校验码，即校验码00至校验码99。从而参考图1B，智能手表20首次从手机10同步联系人信息时，可以从手机1获取10000条联系人信息，采用和手机10相同的方式对该10000条联系人信息进行分组存储，并同时存储各个分组的校验码。Referring to Figure 1A, there are 10,000 pieces of contact information stored in the mobile phone 10. The mobile phone 10 can divide the 10,000 pieces of contact information into 100 groups according to the last two digits of the phone number in the contact information, that is, group 00 to group 99. , and then determine a check code for each group based on the specific content of each group, for example, by performing an XOR operation on the information summary of each contact information in a group to determine the check code of the group, that is, the check code 00 to check code 99. Therefore, referring to Figure 1B, when smart watch 20 synchronizes contact information from mobile phone 10 for the first time, it can obtain 10,000 contact information from mobile phone 1, use the same method as mobile phone 10 to group and store the 10,000 contact information, and store them simultaneously. Check code for each group.
图2A根据本申请的一些实施例，示出了一种智能手表20再次从手机10同步联系人信息的场景示意图。FIG. 2A shows a schematic diagram of a scenario in which the smart watch 20 synchronizes contact information from the mobile phone 10 again according to some embodiments of the present application.
参考图2A，智能手表20再次从手机10同步联系人信息时，主要包括如下步骤：S21智能手表20可以先从手机10中获取各分组的校验码，并将各分组的校验码和智能手表20中相对应的分组的校验码进行对比，确定出校验码不同的差异分组；S22：智能手表20将差异分组的分组标识发送给手机10；S23：手机10响应于接收到的差异分组的分组标识，将差异分组的联系人信息发送给智能手表20，智能手表20将获取的联系人存储在智能手表20中，完成联系人信息同步。例如，参考图2B，假设手机10的分组01的校验码由于分组01中的联系人信息发生变动，例如用户操作手机10修改、删除或新增联系人信息，由校验码01变更为校验码01'，从而智能手表20在从手机10同步联系人信息时，获取到的分组01的校验码为校验码01'，而智能手表20中分组01的校验码为校验码01，两者不同，进而确定出分组01为差异分组。智能手表20只需从手机10中获取分组01中的数据，即可完成联系人的同步，而无需对其他99个分组的联系人进行同步，提升了同步效率。Referring to Figure 2A, when the smart watch 20 synchronizes the contact information from the mobile phone 10 again, it mainly includes the following steps: S21 The smart watch 20 can first obtain the verification code of each group from the mobile phone 10, and combine the verification code of each group with the smart phone 10. The check codes of the corresponding groups in the watch 20 are compared to determine the difference groups with different check codes; S22: The smart watch 20 sends the group identification of the difference group to the mobile phone 10; S23: The mobile phone 10 responds to the received difference The group identification of the group is used to send the contact information of the different groups to the smart watch 20. The smart watch 20 stores the obtained contacts in the smart watch 20 to complete the synchronization of the contact information. For example, referring to Figure 2B, assume that the check code of group 01 of the mobile phone 10 changes due to the contact information in the group 01. For example, the user operates the mobile phone 10 to modify, delete or add contact information, and the check code 01 is changed to the check code. The verification code is 01', so when the smart watch 20 synchronizes the contact information from the mobile phone 10, the verification code of group 01 obtained is the verification code 01', and the verification code of group 01 in the smart watch 20 is the verification code. 01, the two are different, and then group 01 is determined to be the difference group. The smart watch 20 only needs to obtain the data in group 01 from the mobile phone 10 to complete the synchronization of contacts without synchronizing the contacts of the other 99 groups, which improves the synchronization efficiency.
可以理解，源电子设备向目标电子设备同步的数据例如可以是能够便于分组的任意数据，例如条目式数据。其中，条目式数据可以是按条进行存储的任意数据，条目数据可以包括至少一个字段，每条数据中至少一个字段包括具体内容，条目式数据包括但不限于联系人、短信、邮件、备忘录、 即时消息等。具体地例如，假设联系人信息包括姓名、电话号码、工作单位，则联系人信息包括三个字段，即姓名、电话号码和工作单位，对于一条联系人信息，姓名、电话号码和工作单位三个字段可以都有具体内容，也可以只是其中部分字段有具体内容。为便于描述，以下以同步的数据为条目式数据为例进行介绍。It can be understood that the data synchronized by the source electronic device to the target electronic device may be, for example, any data that can be conveniently grouped, such as item-type data. The entry data can be any data stored in items. The entry data can include at least one field, and at least one field in each piece of data includes specific content. The entry data includes but is not limited to contacts, text messages, emails, memos, Instant messaging etc. Specifically, for example, assuming that the contact information includes name, phone number, and work unit, the contact information includes three fields, namely name, phone number, and work unit. For a piece of contact information, there are three fields: name, phone number, and work unit. The fields can all have specific content, or only some of the fields can have specific content. For the convenience of description, the following introduction takes the synchronized data as entry-type data as an example.
为便于理解，首先介绍对条目式数据进行分组的技术方案。To facilitate understanding, the technical solution for grouping entry-based data is first introduced.
如前所述，条目式数据中单条数据包括至少一个字段，因此，手机10可以以其中任意一个字段作为该条目式数据的分组字段，并根据每条数据的分组字段的至少部分内容来确定各条数据的分组。一般地，可以以采用每条数据都有具体内容的字段作为分组字段或通常不会进行修改的字段作为分组字段。例如，在条目式数据为联系人的情况下，分组字段可以是电话号码、姓名等；在条目式数据为短信的情况下，分组字段可以是收信人或发信人的号码；在条目式数据为邮件的情况下，分组字段可以是发件人或收件人的邮箱、姓名等；在条目式数据为备忘录的情况下，分组字段可以是备忘录的创建时间；在条目式数据为即时消息的情况下，分组字段可以是各条消息的发送或接收时间等。电子设备可以利用预设的分组规则，根据分组字段中的至少部分内容来确定各条数据的分组。As mentioned above, a single piece of data in the entry-type data includes at least one field. Therefore, the mobile phone 10 can use any one of the fields as the grouping field of the entry-type data, and determine each piece of data based on at least part of the content of the grouping field of each piece of data. Grouping of data. Generally speaking, you can use fields that have specific content for each piece of data as grouping fields or fields that are usually not modified as grouping fields. For example, when the entry data is a contact, the grouping field can be a phone number, name, etc.; when the entry data is a text message, the grouping field can be the number of the recipient or sender; when the entry data is In the case of emails, the grouping field can be the email address, name, etc. of the sender or recipient; in the case of the item data being a memo, the grouping field can be the creation time of the memo; in the case of the item data being instant messages Below, the grouping field can be the sending or receiving time of each message, etc. The electronic device can use preset grouping rules to determine the grouping of each piece of data based on at least part of the content in the grouping field.
具体地，图3A根据本申请的一些实施例，示出了一种联系人信息的分组存储示意图。如图3A所示，联系人信息的字段至少包括电话号码和姓名，手机10可以根据电话号码来确定各条联系人信息的分组，例如将电话号码的后两位作为各条联系人信息的分组，将手机10中存储的联系人信息分为100组(分组00至分组99)。在一些实施例中，手机10可以为每条联系人信息增加一个分组标识，用于指示各条联系人信息所在的分组，从而手机10中各条联系人信息可以按照任意的顺序存储在存储器中，手机10根据各条联系人信息的分组标识即可确定其所在分组，进而手机10无需更改存储联系人信息的数据结构。在另一些实施例中，手机10也可以将联系人信息进行分区存储，即将一个分组的数据存储于存储器中相邻的区域来提高同一个分组中的数据的访问速度。例如，参考图3B，手机10在存储图3A所示的联系人信息时，可以在存储器中设置100个存储分区，并将同一个分组的联系人信息存储到同一存储分区中，从而手机10可以更快地从存储器中读取同一分组的数据时，提升数据同步的效率。Specifically, FIG. 3A shows a schematic diagram of group storage of contact information according to some embodiments of the present application. As shown in FIG. 3A , the contact information fields at least include a phone number and a name. The mobile phone 10 can determine the grouping of each piece of contact information based on the phone number. For example, the last two digits of the phone number are used as the grouping of each piece of contact information. , the contact information stored in the mobile phone 10 is divided into 100 groups (group 00 to group 99). In some embodiments, the mobile phone 10 can add a group identifier to each piece of contact information to indicate the group in which each piece of contact information is located, so that each piece of contact information in the mobile phone 10 can be stored in the memory in any order. , the mobile phone 10 can determine the group it belongs to according to the group identification of each piece of contact information, and the mobile phone 10 does not need to change the data structure for storing the contact information. In other embodiments, the mobile phone 10 can also partition the contact information, that is, store the data of one group in adjacent areas in the memory to improve the access speed of data in the same group. For example, referring to Figure 3B, when the mobile phone 10 stores the contact information shown in Figure 3A, it can set 100 storage partitions in the memory, and store the contact information of the same group in the same storage partition, so that the mobile phone 10 can Improve the efficiency of data synchronization when reading data of the same group from memory faster.
可以理解，在一些实施例中，手机10也可以不先对联系人信息进行分组存储，只是利用联系人信息的分组字段确定出分组00至分组99的校验码，从而手机10可以不对手机10存储的联系人信息的数据结构进行调整，例如为每条联系人信息增加分组标识或将同一分组的联系人信息存储于存储器中的相邻区域，只用维护不同分组的校验码，即可通过本申请各实施例提供的数据同步方法和其他电子设备按分组进行数据同步。It can be understood that in some embodiments, the mobile phone 10 may not store the contact information in groups first, but only uses the grouping field of the contact information to determine the check codes of group 00 to group 99, so that the mobile phone 10 may not store the contact information in groups. Adjust the data structure of the stored contact information, for example, add a group identifier to each piece of contact information or store the contact information of the same group in an adjacent area in the memory, and only need to maintain the check codes of different groups. The data synchronization method provided by each embodiment of the present application is used to perform data synchronization on a group basis with other electronic devices.
可以理解，在另一些实施例中，也可以使用电话号码字段的其他位来确定联系人信息的分组，还可以使用联系人信息的其他字段来确定联系人信息的分组，在此不做限定。It can be understood that in other embodiments, other bits of the phone number field can also be used to determine the grouping of contact information, and other fields of the contact information can also be used to determine the grouping of contact information, which is not limited here.

Referring to Figure 4A, the memo includes at least two fields: creation time and memo content. The mobile phone 10 can use the creation time of the memo as a grouping field to determine the grouping of each memo. For example, determine the grouping of each memo based on the seconds corresponding to the creation time of each memo. Grouping of memos, divide memos into 60 groups. Or, take the remainder of 10 from the number of milliseconds corresponding to the creation time of each memo, and divide the memos into 100 groups.
可以理解，在另一些实施例中，也可以使用创建时间的其他位来确定备忘录的分组，还可以使用备忘录的其他字段来确定备忘录的分组，在此不做限定。It can be understood that in other embodiments, other bits of the creation time can also be used to determine the grouping of the memo, and other fields of the memo can also be used to determine the grouping of the memo, which is not limited here.
又例如，图4B示出了一种邮件的分组存储示意图。参考图4B，邮件至少包括发件人/收件人和内容两个字段，电子设备以发件人/收件人为分组字段，确定各封邮件的分组，例如根据发件人或收 件人的电子邮件地址的首字母对应的美国信息交换标准代码(American Standard Code for Information Interchange，ASCII)的后两位，将各封邮件分为100组。As another example, FIG. 4B shows a schematic diagram of group storage of emails. Referring to Figure 4B, the email includes at least two fields: sender/recipient and content. The electronic device uses sender/recipient as the grouping field to determine the grouping of each email, for example, according to the sender or recipient. Each email is divided into 100 groups based on the last two digits of the American Standard Code for Information Interchange (ASCII) corresponding to the first letter of the sender's email address.
可以理解，在另一些实施例中，也可以使用发件人/收件人字段的其他位来确定邮件的分组，还可以使用邮件的其他字段来确定邮件的分组，在此不做限定。It can be understood that in other embodiments, other bits of the sender/recipient field can also be used to determine the grouping of emails, and other fields of the email can also be used to determine the grouping of emails, which is not limited here.
再例如，图4C示出了一种短信的分组存储示意图。参考图4C，短信至少包括发信人/收信人号码、内容两个字段，手机10可以以短信的发信人/收信人号码字段为分组字段，确定各条短信的分组，例如将发信人/收信人号码字段中的后两位作为分组，将短信为100组。As another example, FIG. 4C shows a schematic diagram of group storage of short messages. Referring to Figure 4C, a text message includes at least two fields: sender/recipient number and content. The mobile phone 10 can use the sender/recipient number field of the text message as a grouping field to determine the grouping of each text message, for example, the sender/recipient.

例如，参考图3A，对于联系人信息，手机10可以将电话号码字段作为分组字段，并将电话号码的后2位作为各条数据的分组，将联系人信息分为100组；又例如，参考图4A，对于备忘录，可以以备忘录的创建时间为分组字段，将备忘录的创建时间的秒位作为各条备忘录的分组字段，将备忘录分为60组；又例如，参考图4B,对于邮件，可以将邮件的发件人/收件人的电子邮件地址的首字母的ASCII码的后2位作为分组字段，将邮件分为100组；再例如，参考图4C，对于短信，可以以发信人/收信人号码为分组字段，以发信人/收信人号码的后两位作为分组，将短信分为100组。For example, referring to Figure 3A, for contact information, the mobile phone 10 can use the phone number field as a grouping field, and use the last 2 digits of the phone number as a grouping of each piece of data to divide the contact information into 100 groups; for another example, refer to Figure 4A, for memos, the creation time of the memo can be used as the grouping field, and the seconds of the memo's creation time can be used as the grouping field of each memo, and the memos can be divided into 60 groups; for another example, referring to Figure 4B, for emails, you can Use the last 2 digits of the ASCII code of the first letter of the email address of the sender/recipient of the email as the grouping field to divide the email into 100 groups; for another example, refer to Figure 4C, for text messages, you can use the sender/ The recipient number is a grouping field, and the last two digits of the sender/recipient number are used as groups to divide the text messages into 100 groups.
可以理解，在另一些实施例中，也可以采用其他字段对各类条目式数据进行分组，在此不做限定。It can be understood that in other embodiments, other fields may also be used to group various types of entry-type data, which is not limited here.
可以理解，手机10在确定出各条数据的分组后，可以对各条数据进行分组存储，例如，参考图3A，手机10可以为各条联系人信息增加一个分组标识，用于指示各条联系人数据的分组，从而不需要对存储的各条联系人信息的存储位置和结构进行调整；又例如，参考图3B，手机10可以在存储器中设置多个存储分区，并将属于同一分组的联系人信息存储器在同一个存储分区中，从而可以提高手机10从存储器中读取同一分组的数据的速度，提升手机10向其他电子设备发送同一分组中的数据的速度。It can be understood that after determining the grouping of each piece of data, the mobile phone 10 can group and store each piece of data. For example, referring to Figure 3A, the mobile phone 10 can add a grouping identifier to each piece of contact information to indicate each piece of contact. Grouping of personal data, so that there is no need to adjust the storage location and structure of each stored contact information; for another example, referring to Figure 3B, the mobile phone 10 can set multiple storage partitions in the memory, and store contacts belonging to the same group The personal information memory is in the same storage partition, which can increase the speed of the mobile phone 10 reading data in the same group from the memory and improve the speed of the mobile phone 10 sending data in the same group to other electronic devices.
S503：确定各分组中各条数据的消息摘要。 S503: Determine the message digest of each piece of data in each group.
示例性地，手机10可以通过前述MD4、MD5、SHA-1等消息摘要算法确定各条数据的消息摘要，该消息摘要可以用于确定各分组的校验码。For example, the mobile phone 10 can determine the message digest of each piece of data through the aforementioned message digest algorithms such as MD4, MD5, SHA-1, etc., and the message digest can be used to determine the check code of each packet.
例如，对于前述图3A所示的联系人信息中，利用MD5算法得到的第1条联系人信息“123456798LILY”的消息摘要为32位的16进制数“0FA340B963445F53D9EFC042E39AB3AA”(32位16进制数对应于128位二进制数)，利用MD5算法得到第1001条联系人信息“123457698RALPH”的息摘要为32位的16进制数“EF93E986151D6912858BF5BE101E4029”。For example, in the contact information shown in Figure 3A, the message digest of the first contact information "123456798LILY" obtained using the MD5 algorithm is a 32-bit hexadecimal number "0FA340B963445F53D9EFC042E39AB3AA" (32-bit hexadecimal number corresponds to (based on a 128-bit binary number), use the MD5 algorithm to obtain the information summary of the 1001st contact information "123457698RALPH" which is a 32-bit hexadecimal number "EF93E986151D6912858BF5BE101E4029".
S504：根据各分组中各条数据的消息摘要，确定各分组的校验码。S504: Determine the check code of each group based on the message digest of each piece of data in each group.
示例性地，手机10可以根据步骤S503确定出的各条数据的消息摘要，将各条数据的消息摘要进行逻辑运算(例如与、或、非、异或等)或算术运算(例如加、减、乘、除等)，得到各个分组的校验码。For example, the mobile phone 10 can perform logical operations (such as AND, OR, NOT, XOR, etc.) or arithmetic operations (such as addition, subtraction) on the message digest of each piece of data determined in step S503. , multiplication, division, etc.) to obtain the check code of each group.
在一些实施例中，手机10可以将一个分组中的各条数据的消息摘要逐个进行异或运算，来得到各分组的校验码。例如，假设某个分组中包括n条数据，第i条数据的消息摘要为Hashi,则该分组的校验码可以标识为Hash1⊕Hash2⊕……⊕Hashn(⊕为异或运算符)，其中各条数据的消息摘要的顺序可以任意调整。具体地例如，前述图3A中分组98中包括第1条联系人信息和第1001条联系人信息，则分组98的校验码为该两条联系人信息的消息摘要的异或运算结果，即0FA340B963445F53D9EFC042E39AB3AA⊕EF93E986151D6912858BF5BE101E4029＝D11EEB639BC9B20AE321AF1CF384F383。In some embodiments, the mobile phone 10 can perform XOR operations on the message digests of each piece of data in a group one by one to obtain the check code of each group. For example, assuming that a certain group includes n pieces of data, and the message digest of the i-th piece of data is Hash i , then the check code of the group can be identified as Hash 1 ⊕Hash 2 ⊕...⊕Hash n (⊕ is an exclusive OR operation symbol), the order of the message digest of each piece of data can be adjusted arbitrarily. For example, if the group 98 in Figure 3A includes the first piece of contact information and the 1001st piece of contact information, then the check code of the group 98 is the XOR operation result of the message digests of the two pieces of contact information, that is, 0FA340B963445F53D9EFC042E39AB3AA⊕EF93E986151D6912858BF5BE101E4029＝D11EEB639BC9B20AE321AF1CF384F383.
可以理解，在另一些实施例中，也可以通过其他方式来确定各分组的校验码，在此不做限定。It can be understood that in other embodiments, the check code of each group can also be determined in other ways, which is not limited here.
可以理解，在一些实施例中，手机10可以维护一个数据用于存储各分组的校验码，例如可以用一个包括k个元素的向量，来存储各分组的校验码，其中k为分组的数量，从而该向量中的一个元素可以对应于一个分组的校验码。It can be understood that in some embodiments, the mobile phone 10 can maintain a data for storing the check code of each group. For example, a vector including k elements can be used to store the check code of each group, where k is the group. Quantity, so that one element in the vector can correspond to the check code of a group.
可以理解，手机10在首次对条目式数据进行分组存储时，可以通过前述步骤S501至步骤S504来得到各条数据的分组及各分组的校验码，并在首次将分组存储的条目式数据同步给其他电子设备，例如前述智能手表20时，将各分组中的数据及各分组的校验码发送给智能手表20。It can be understood that when the mobile phone 10 groups and stores the entry-type data for the first time, it can obtain the grouping of each piece of data and the check code of each group through the aforementioned steps S501 to S504, and synchronizes the grouped storage of the entry-type data for the first time. When sending the data to other electronic devices, such as the aforementioned smart watch 20 , the data in each group and the verification code of each group are sent to the smart watch 20 .
可以理解，前述步骤S501至步骤S504的执行顺序只是一种示例，在另一些实施例中，可以调整部分步骤的执行顺序，也可以拆分或组合部分步骤，在此不做限定。例如前述步骤S502和步骤S503的顺序可以交换、前述步骤S503和步骤504可以合并等。It can be understood that the execution order of steps S501 to S504 is just an example. In other embodiments, the execution order of some steps can be adjusted, and some steps can be split or combined, which is not limited here. For example, the order of the aforementioned steps S502 and step S503 can be exchanged, the aforementioned steps S503 and step 504 can be combined, and so on.
下面介绍手机10在对条目式数据进行维护时，更新各分组的校验码的技术方案。The following describes the technical solution for the mobile phone 10 to update the check codes of each group when maintaining the entry-type data.
具体地，图6根据本申请的一些实施例，示出了一种分组校验码的更新方法流程示意图。该流程的执行主体为手机10，例如手机10中的至少一个应用程序或服务，如图6所示，该流程包括如下步骤。Specifically, FIG. 6 shows a schematic flowchart of a method for updating a group check code according to some embodiments of the present application. The execution subject of this process is the mobile phone 10, for example, at least one application or service in the mobile phone 10. As shown in Figure 6, the process includes the following steps.
S601：检测到对条目式数据的维护操作。S601: Maintenance operation on entry-based data is detected.
示例性地，手机10可以在检测到用户对条目式数据的维护操作的情况下，通过执行以下步骤S602至步骤S606来更新各个分组的校验码。For example, the mobile phone 10 may update the check codes of each group by performing the following steps S602 to S606 when detecting the user's maintenance operation on the entry-type data.
可以理解，对条目式数据的维护操作包括但不限于新增、删除、修改。It can be understood that maintenance operations on entry-type data include but are not limited to adding, deleting, and modifying.
例如，图7A示出手机10中显示的畅连TM应用的联系人界面示意图，用户可以通过点击“增加”控件70，进入图7B所示的选项界面，该选项界面中包括选项菜单71；用户可以通过对“添加联系人”控件711的点击来添加联系人(即新增操作)，手机10在检测到用户对“添加联系人”控件711的点击操作后，即可检测到对条目式数据的维护操作。 For example, Figure 7A shows a schematic diagram of the contact interface of the Changlian TM application displayed on the mobile phone 10. The user can click the "Add" control 70 to enter the option interface shown in Figure 7B, which includes an option menu 71; Contacts can be added by clicking on the "Add Contact" control 711 (i.e., adding a new operation). After detecting the user's click operation on the "Add Contact" control 711, the mobile phone 10 can detect entry data maintenance operations.
又例如，用户可以在图7A所示的联系人界面中查看一个联系人的详细信息，例如通过点击JIM的头像，进入到图7C所示的JIM的联系人详情界面，用户可以通过对“选项”控件72的点击操作，进入图7D所示的选项界面，该选项界面中包括选项菜单73；用户可通过对“编辑联系人”控件731的操作来编辑JIM的联系人信息、通过对“删除联系人”控件732的操作来删除JIM的联系人信息。从而手机10在检测到用户“对编辑联系人”控件731或“删除联系人”控件732的操作后，可以检测到对条目式数据的维护操作。For another example, the user can view the detailed information of a contact in the contact interface shown in Figure 7A, for example, by clicking on JIM's avatar to enter the JIM contact details interface shown in Figure 7C. The user can click on the "option" "Click operation on the control 72 to enter the option interface shown in Figure 7D, which includes an option menu 73; the user can edit JIM's contact information by operating the "Edit Contact" control 731, and by operating the "Delete" The operation of "Contact" control 732 is to delete JIM's contact information. Therefore, after detecting the user's operation of the "edit contact" control 731 or the "delete contact" control 732, the mobile phone 10 can detect the maintenance operation of the entry-type data.
可以理解，以上所示手机10检测到对条目式数据的维护操作的情况只是一种示例，在另一些实施例中，针对不同的条目式数据，不同的应用程序或服务，手机10也可以在其他情形下检测到对条目式数据的维护操作，在此不做限定。It can be understood that the situation where the mobile phone 10 detects the maintenance operation on the entry data shown above is just an example. In other embodiments, for different entry data, different applications or services, the mobile phone 10 can also perform maintenance operations on the entry data. Maintenance operations on entry-based data are detected in other situations, which are not limited here.
S602：确定维护操作的类型。S602: Determine the type of maintenance operation.
示例性地，手机10检测到用户对条目式数据的维护操作后，可以确定出维护操作的类型。在确定出维护操作为新增或删除的情况下，转至步骤S603；在确定出维护操作为修改的情况下，转至步骤S605。For example, after the mobile phone 10 detects the user's maintenance operation on the entry-type data, the type of the maintenance operation can be determined. If it is determined that the maintenance operation is adding or deleting, go to step S603; if it is determined that the maintenance operation is modifying, go to step S605.
可以理解，维护操作的类型可以包括新增、删除和修改，针对不同类型的维护操作，手机10可以采用不同的方式来更新维护操作对应的目标分组的校验码。It can be understood that the types of maintenance operations may include addition, deletion, and modification. For different types of maintenance operations, the mobile phone 10 may use different methods to update the check code of the target group corresponding to the maintenance operation.
S603：确定新增或删除的目标数据所对应的目标分组。S603: Determine the target group corresponding to the newly added or deleted target data.
示例性地，手机10可以根据用户新增的目标数据中的分组字段，确定新增的目标数据对应的目标分组，或者根据用户删除的目标数据的分组标识确定删除操作的目标数据对应的目标分组。For example, the mobile phone 10 can determine the target group corresponding to the newly added target data according to the group field in the target data added by the user, or determine the target group corresponding to the target data of the deletion operation based on the group identification of the target data deleted by the user. .
例如，手机10在新增一个联系人信息时，可以根据用户输入的新增的联系人信息的电话号码的后两位确定目标分组，例如，假设新增的联系人的电话号码为“123684798”，新增的联系人信息对应的目标分组为分组98，又例如，假设用户删除的联系人信息为LILY的联系人信息，则参考图3A可知LILY的联系人信息对应的目标分组为分组98。For example, when the mobile phone 10 adds a new contact information, the target group can be determined based on the last two digits of the phone number of the new contact information input by the user. For example, assume that the phone number of the new contact is "123684798" , the target group corresponding to the newly added contact information is group 98. For another example, assuming that the contact information deleted by the user is LILY's contact information, referring to Figure 3A, it can be seen that the target group corresponding to LILY's contact information is group 98.
S604：确定目标数据的消息摘要，并基于目标数据的消息摘要更新目标分组的校验码。S604: Determine the message digest of the target data, and update the check code of the target packet based on the message digest of the target data.
手机10根据用户新增的数据或删除的数据的具体内容，确定出目标数据的消息摘要，并基于该消息摘要更新目标分组的校验码。The mobile phone 10 determines the message summary of the target data based on the specific content of the user's newly added data or deleted data, and updates the check code of the target group based on the message summary.
例如，假设用户新增的联系人信息为“123684798KATE”(即新增的联系人的姓名为KATE，电话号码为123684798),则利用MD5算法得到的目标数据的消息摘要为：2566590C52CB05017DB7A3E3A102C392；又例如，假设用户删除的联系人信息为LILY的联系人信息，则利用MD5算法得到的目标数据的消息摘要为：0FA340B963445F53D9EFC042E39AB3AA。For example, assuming that the contact information added by the user is "123684798KATE" (that is, the name of the new contact is KATE and the phone number is 123684798), the message summary of the target data obtained by using the MD5 algorithm is: 2566590C52CB05017DB7A3E3A102C392; for another example, Assuming that the contact information deleted by the user is LILY's contact information, the message digest of the target data obtained using the MD5 algorithm is: 0FA340B963445F53D9EFC042E39AB3AA.
可以理解，手机10在更新分组的校验码过程中确定目标数据的消息摘要的方法，与手机10首次生成分组存储的条目式数据各分组的校验码采用的计算各条数据的消息摘要的方法应当相同。It can be understood that the method used by the mobile phone 10 to determine the message digest of the target data in the process of updating the check code of the group is the same as the method used by the mobile phone 10 to calculate the message digest of each piece of data when it first generates the check code of each group of entry-type data stored in the group. The approach should be the same.
在确定出目标数据的消息摘要后，手机10可以将目标数据的消息摘要和目标分组的校验码进行异或运算，并将运算结果作为目标分组的新校验码。例如，在维护操作为删除LILY的联系人信息的情况下，手机10可以将前述目标数据的消息摘要0FA340B963445F53D9EFC042E39AB3AA与前述步骤S504中得到的分组98的校验码D11EEB639BC9B20AE321AF1CF384F383进行异或运算，得到新的校验码EF93E986151D6912858BF5BE101E4029；又例如，在维护操作为新增KATE的联系人信息的情况下，手机10可以将前述目标数据的消息摘要2566590C52CB05017DB7A3E3A102C392与前述步骤S504中得到的分组98的校验码D11EEB639BC9B20AE321AF1CF384F383进行异或运算，得到新的校验码D3488EF35EE50808184EE10752863011。如此，对于一条数据的新增或删除，手机10通过一次异或运 算即可更新目标分组的校验码，运算量少，更新速度快。After determining the message digest of the target data, the mobile phone 10 can perform an XOR operation on the message digest of the target data and the check code of the target group, and use the operation result as a new check code of the target group. For example, when the maintenance operation is to delete LILY's contact information, the mobile phone 10 can perform an XOR operation on the message digest 0FA340B963445F53D9EFC042E39AB3AA of the aforementioned target data and the check code D11EEB639BC9B20AE321AF1CF384F383 of group 98 obtained in the aforementioned step S504 to obtain a new checksum. The verification code is EF93E986151D6912858BF5BE101E4029; for another example, when the maintenance operation is to add the contact information of KATE, the mobile phone 10 can combine the message digest 2566590C52CB05017DB7A3E3A102C392 of the aforementioned target data with the verification code D11EEB639BC9B20 of group 98 obtained in the aforementioned step S504. AE321AF1CF384F383 XOR After calculation, the new check code D3488EF35EE50808184EE10752863011 is obtained. In this way, for the addition or deletion of a piece of data, the mobile phone 10 performs an XOR operation The check code of the target group can be updated by calculation, which requires less calculation and fast update speed.
可以理解，在另一些实施例中，手机10也可以通过其他方式来更新校验码，例如将目标分组中的各条数据的消息摘要进行异或来重新计算目标分组的校验码，具体可以参考前述步骤S504，在此不做赘述。It can be understood that in other embodiments, the mobile phone 10 can also update the check code in other ways, such as XORing the message digest of each piece of data in the target group to recalculate the check code of the target group. Specifically, Refer to the aforementioned step S504, which will not be described again here.
S605：确定进行修改操作的目标数据对应的目标分组。S605: Determine the target group corresponding to the target data for modification operation.
示例性地，手机10根据用户进行修改操作目标数据的分组标识，确定进行修改操作的目标数据对应的目标分组。For example, the mobile phone 10 determines the target group corresponding to the target data for the modification operation based on the group identification of the target data for the modification operation by the user.
例如，手机10在确定修改操作对应的字段不是分组字段的情况下，可以根据修改操作对应的联系人信息的分组标识来确定目标分组。例如用户修改的联系人信息为LILY的联系人信息，则参考图3A可知LILY的联系人信息对应的目标分组为分组98。For example, when the mobile phone 10 determines that the field corresponding to the modification operation is not a group field, the mobile phone 10 may determine the target group according to the group identifier of the contact information corresponding to the modification operation. For example, the contact information modified by the user is LILY's contact information. Referring to FIG. 3A , it can be seen that the target group corresponding to LILY's contact information is group 98.
又例如，手机10在确定修改操作对应的字段是分组字段的情况下，目标分组可以包括两个分组：一个是修改操作对应的联系人信息的分组标识对应的分组(以下称为第一目标分组)，另一个是根据修改后的分组字段确定的分组(以下称为第二目标分组)。具体地，参考图3A，假设修改操作将LILY的联系人信息中的电话号码由123456798修改为123654720，则第一目标分组可以是LILY的联系人信息中的分组标识对应分组98、第二目标分组可以是修改后的电话号码123654720对应的分组20。For another example, when the mobile phone 10 determines that the field corresponding to the modification operation is a group field, the target group may include two groups: one is a group corresponding to the group identifier of the contact information corresponding to the modification operation (hereinafter referred to as the first target group). ), and the other is a group determined based on the modified grouping field (hereinafter referred to as the second target group). Specifically, referring to Figure 3A, assuming that the modification operation modifies the phone number in LILY's contact information from 123456798 to 123654720, the first target group can be the group ID corresponding to the group 98 in LILY's contact information, the second target group It can be group 20 corresponding to the modified phone number 123654720.
S606：确定目标数据在修改前和修改后的消息摘要，并基于目标数据在修改前和修改后的消息摘要更新目标分组的校验码。S606: Determine the message digest of the target data before modification and after modification, and update the check code of the target group based on the message digest of the target data before modification and after modification.
示例性地，手机10确定目标数据在修改前和修改后的消息摘要，并基于目标数据在修改前和修改后的消息摘要更新目标分组校验码。For example, the mobile phone 10 determines the message digest of the target data before modification and after modification, and updates the target packet check code based on the message digest of the target data before modification and after modification.
例如，手机10在修改操作对应的字段不是分组字段的情况下，可以先将目标数据在修改前的消息摘要与目标分组的校验码进行异或运算，再将运算结果与目标数据在修改后的消息摘要进行异或运算，得到目标分组的新校验码。如此，对于一条数据的修改，手机10通过两次异或运算即可更新目标分组的校验码，运算量少，更新速度快。For example, when the field corresponding to the modification operation of the mobile phone 10 is not a grouping field, the mobile phone 10 can first perform an XOR operation on the message digest of the target data before modification and the check code of the target group, and then perform an XOR operation on the operation result and the target data after modification. Perform XOR operation on the message digest to obtain the new check code of the target group. In this way, for the modification of a piece of data, the mobile phone 10 can update the check code of the target group through two XOR operations, which requires less calculation and fast update speed.
具体地，假设目标数据为LILY的联系人信息，目标分组为前述分组98，LILY的联系人信息修改后为“123456798135654525LILY”(即新增一个电话号码135654525)，则利用MD5算法可以得到目标数据修改后的消息摘要为7E327F6E3E117847411E52B2D9B0B3CE。从而手机10可以先将前述目标数据修改前的消息摘要0FA340B963445F53D9EFC042E39AB3AA与前述分组98的校验码D11EEB639BC9B20AE321AF1CF384F383进行异或运算，得到运算结果EF93E986151D6912858BF5BE101E4029，再将该运算结果与修改后的消息摘要7E327F6E3E117847411E52B2D9B0B3CE进行异或运算，得到目标分组的新校验码F01F765D9A99AE06AB98C210C9AEF3E7。Specifically, assuming that the target data is LILY's contact information, the target group is the aforementioned group 98, and LILY's contact information is modified to "123456798135654525LILY" (that is, a new phone number 135654525 is added), then the MD5 algorithm can be used to obtain the target data modification The final message digest is 7E327F6E3E117847411E52B2D9B0B3CE. Therefore, the mobile phone 10 can first perform an XOR operation on the message digest 0FA340B963445F53D9EFC042E39AB3AA before the modification of the target data and the check code D11EEB639BC9B20AE321AF1CF384F383 of the aforementioned group 98 to obtain the operation result EF93E986151D6912858BF5BE101E4029, and then perform the operation The result is XORed with the modified message digest 7E327F6E3E117847411E52B2D9B0B3CE , get the new check code F01F765D9A99AE06AB98C210C9AEF3E7 of the target group.
又例如，手机10在修改操作对应的字段是分组字段的情况下，修改操作实际可以分解为在第一目标分组中的删除操作和在第二目标分组中的新增操作，从而手机10可以将第一目标分组的校验码更新为目标数据修改前的消息摘要和第一目标分组的当前校验码的异或运算结果、将第二目标分组的校验码更新为目标数据修改后的消息摘要和第二目标分组的当前校验码的异或运算结果。For another example, when the field corresponding to the modification operation of the mobile phone 10 is a group field, the modification operation can actually be decomposed into a deletion operation in the first target group and a new operation in the second target group, so that the mobile phone 10 can The check code of the first target group is updated to the XOR operation result of the message digest before the target data is modified and the current check code of the first target group, and the check code of the second target group is updated to the message after the target data is modified. The XOR operation result of the digest and the current check code of the second target group.
具体地，假设目标数据为LILY的联系人信息，修改操作为将LILY的电话号码由123456798修改为123654720，则目标数据修改后的消息摘要为：利用MD5算法得到的“123654720LILY”对应的消息摘要：613AC4F4E14A19583B05EACD3EF51357。手机10可以将前述目标数据修改前的消息摘要0FA340B963445F53D9EFC042E39AB3AA与分组98的当前校验码D11EEB639BC9B20AE321AF1CF384F383 做异或运算，得到分组98的新校验码EF93E986151D6912858BF5BE101E4029。手机10还可以将目标数据修改后的消息摘要613AC4F4E14A19583B05EACD3EF51357，与分组20当前的校验码9123674BA490B1E6CB5F45536BC8DEE2做异或运算，得到分组20的新校验码F019A3BF45DAA8BEF05AAF9E553DCDB5。可以理解，在另一些实施例中，手机10也可以通过其他方式来更新目标分组的校验码，例如将进行维护操作后的目标数据中的各条数据的消息摘要逐个进行异或运算来更新目标分组的校验码，在此不做限定。Specifically, assuming that the target data is LILY's contact information, and the modification operation is to modify LILY's phone number from 123456798 to 123654720, then the modified message summary of the target data is: the message summary corresponding to "123654720LILY" obtained using the MD5 algorithm: 613AC4F4E14A19583B05EACD3EF51357. Mobile phone 10 can combine the message digest 0FA340B963445F53D9EFC042E39AB3AA before the aforementioned target data modification with the current check code D11EEB639BC9B20AE321AF1CF384F383 of group 98. Do XOR operation to get the new check code EF93E986151D6912858BF5BE101E4029 of group 98. Mobile phone 10 can also perform an XOR operation on the modified message digest 613AC4F4E14A19583B05EACD3EF51357 of the target data and the current check code 9123674BA490B1E6CB5F45536BC8DEE2 of group 20 to obtain the new check code F019A3BF45DAA8BEF05AAF9E553DCDB5 of group 20. It can be understood that in other embodiments, the mobile phone 10 can also update the check code of the target group through other methods, such as performing an XOR operation on the message digests of each piece of data in the target data after the maintenance operation is performed one by one to update.

The smart watch 20 can identify the group corresponding to a certain check code X in the smart watch 20 and does not exist in the received In the case of the group identification corresponding to each check code X, the group corresponding to the check code X is determined to be the second type of difference group. For example, assuming that the smart watch 20 has a packet with a packet ID of 98, but the received packet IDs corresponding to each check code sent by the mobile phone 10 do not have 98, it means that the packet 98 is a second type of difference packet.
第三类差异分组，手机10和智能手表20中都存在、但校验码不同的分组，智能手表20可以在智能手表20中存在校验码为Y的分组的分组标识，与接收到的校验码X对应的分组的分组标识相同，但该校验码X与校验码Y不同的情况下，确定校验码X对应的分组为第三类差异分组。例如，假设智能手表20接收到的校验码F019A3BF45DAA8BEF05AAF9E553DCDB5对应的分组的分组标识为98，而智能手表20中分组标识为98的分组的校验码为D11EEB639BC9B20AE321AF1CF384F383，则分组98为第三类差异分组。The third type of differential grouping is a grouping that exists in both the mobile phone 10 and the smart watch 20 but has different verification codes. The smart watch 20 can have a group identification of a group with a verification code Y in the smart watch 20, which is the same as the received verification code. When the group identifiers of the groups corresponding to the check code X are the same, but the check code X and the check code Y are different, the group corresponding to the check code For example, assume that the group ID of the group corresponding to the check code F019A3BF45DAA8BEF05AAF9E553DCDB5 received by the smart watch 20 is 98, and the check code of the group with the group ID 98 in the smart watch 20 is D11EEB639BC9B20AE321AF1CF384F383, then group 98 is the third type of difference group.
