Background

With the rapid development of internet technology, intelligent terminals such as smart phones are more and more popular, and the intelligent terminals become a main tool for people to share information.

At present, the sharing method based on the intelligent terminal mainly includes copying characters, screenshot, sending a file, sending a Uniform Resource Locator (URL), a two-dimensional Code (QR Code), and the like. The two-dimensional code has a fault-tolerant function, and if the two-dimensional code picture is partially shielded, the two-dimensional code picture can still be scanned by the intelligent terminal. Therefore, compared with other sharing methods, the two-dimensional code sharing method is more convenient, but the problem of information leakage also exists. For example, the user a may send a two-dimensional code containing a personal contact phone to the user B, so that the user B may obtain the personal contact phone of the user a by scanning the two-dimensional code. If the user B sends the two-dimensional code to other users, the other users can also obtain the contact call of the user A, and further telephone harassment can be carried out on the user A.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example one

The embodiment discusses the information sharing method provided by the invention based on the generation process of the two-dimensional code.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of the information sharing method of the present invention is shown, which may specifically include the following steps:

step 101, grading the shared information content, and determining an encryption level corresponding to each type of data in the information content.

As a specific application of the present invention, an intelligent terminal, such as a mobile phone, a tablet computer, a Personal Computer (PC), etc., can convert information content that a user needs to share into a two-dimensional Code (QR Code), so that the user can share information using the QR Code.

In the embodiment of the invention, the intelligent terminal can determine the corresponding information content according to the operation of the user, and can use the determined information content as the shared information content, so that the information content can be classified according to the preset classification standard, and the encryption level corresponding to each type of data in the information content can be determined. The encryption level may specifically include a first level, a second level, a third level, and the like, where the third level may be higher than the second level, and the second level may be higher than the first level, and the setting of the encryption level is not specifically limited by the present invention.

And 102, configuring corresponding target users for the second level.

In this embodiment, the intelligent terminal may set a target user corresponding to each encryption level based on user information input by an operation user, so that a user or a terminal that acquires data at each encryption level may be respectively limited. The user information may be used to identify a corresponding user or terminal, such as any one or more of an Identity number (ID), a user name, an Internet Protocol (IP) address, an equipment Identity, and the like, which is not limited in this embodiment of the present invention.

As a specific example of the present invention, when detecting that user information is input for a second level or data of the second level, the intelligent terminal may configure a corresponding target user for the second level according to the user information, for example, a user corresponding to a user name is used as a target user, so that a user reading data of the second level may be limited, and other users are prevented from illegally acquiring data of the second level; or the terminal corresponding to the equipment identification code is taken as a target user, so that the intelligent terminal for reading the second-level data can be limited, and other terminals are prevented from illegally acquiring the second-level data. Wherein the target user may have the right to read the second level of data.

And 103, performing partition storage on each type of data according to the encryption level to generate a characteristic two-dimensional code corresponding to the target user.

The intelligent terminal can determine the storage position of each type of data in two dimensions based on the encryption level corresponding to the type of data in the generation process of the two-dimensional code. Specifically, the intelligent terminal may preset the partition corresponding to each encryption level, so that the data of each encryption level may be respectively encapsulated into the corresponding partition based on the encryption level in the process of generating the two-dimensional code, and then the corresponding characteristic two-dimensional code is generated by synthesizing all the partitions. The characteristic two-dimensional code may contain user information, and the contained user information may be used to determine a corresponding characteristic user.

And 104, sharing according to the characteristic two-dimensional code.

After the intelligent terminal generates the characteristic two-dimensional code, the characteristic two-dimensional code can be fed back to the user, so that the user can share information by adopting the characteristic two-dimensional code. For example, the intelligent terminal can display the characteristic two-dimensional code on a display interface, so that other intelligent terminals can scan the characteristic two-dimensional code; the characteristic two-dimensional code can also be sent to the target terminal through an application program such as instant messaging software, so that the target terminal can receive the characteristic two-dimensional code and obtain information content carried by the characteristic two-dimensional code by scanning the characteristic two-dimensional code, and the purpose of information sharing is achieved. Of course, the intelligent terminal may also share the characteristic two-dimensional code with other terminals in other manners, and if the characteristic two-dimensional code is printed out, other users may scan the printed characteristic two-dimensional code.

According to the invention, the information content to be shared is classified, so that the data of each encryption level can be stored in a partition mode according to the encryption level, and the characteristic two-dimensional code corresponding to the characteristic user is generated. The characteristic user can be used for limiting users for acquiring data of the second level in the characteristic two-dimensional code, so that the problem of information leakage in a two-dimensional code sharing mode is solved, and information safety is guaranteed.

Referring to fig. 2, a flowchart illustrating steps of an alternative embodiment of the information sharing method according to the present invention is shown, and specifically may include the following steps:

step 201, the shared information content is graded, and the encryption level corresponding to each type of data in the information content is determined.

The intelligent terminal grades the shared information content, and determines an encryption level corresponding to each type of data in the information content, which may specifically include: for each type of data in the information content, determining a corresponding encryption level based on an input level selection operation; or detecting keywords in each type of data to determine the corresponding encryption level. Wherein the encryption level may include a first level and a second level, and the first level is lower than the second level.

Specifically, the intelligent terminal can divide the shared information content into the following according to the importance degree related to the privacy of the user: the privacy degree is public information without confidentiality, private information with the privacy degree of general confidentiality and absolute information with the privacy degree of absolute confidentiality; and setting the encryption level corresponding to each privacy degree, wherein if the confidentiality is not required to correspond to the first level, the confidentiality and the confidentiality are generally corresponding to the second level. The second level of data may specifically include: confidential information and private information.

Taking sharing a personal business card as an example, as shown in fig. 3, the business card to be shared may specifically include: the "name", "hobby", the account number of the communication software such as "QQ", "microblog", the "address", and the "personal phone" and the like. The intelligent terminal can grade the information content of the business card according to the operation of the user and determine the encryption level corresponding to each type of data, for example, the encryption level of the name and the like is set to be a first level corresponding to 'no secrecy' according to the privacy degree selected by the user aiming at the name and the like and 'no secrecy'; setting the encryption levels of the QQ, the microblog and the address as a second level corresponding to the general secrecy according to the privacy degree selected by the user aiming at the QQ, the microblog and the address as the general secrecy; and setting the encryption level of the personal telephone to a second level corresponding to the absolute secret according to the privacy degree selected by the user for the personal telephone as the absolute secret.

Of course, the intelligent terminal may also determine the encryption level corresponding to each type of data in the information content by detecting the shared information content. Specifically, the intelligent terminal detects keywords in various types of data in the business card to be shared, so that the security level corresponding to the type of data can be determined according to the preset privacy degree corresponding to the detected keywords, and if the keyword of 'telephone' is detected, the encryption level corresponding to the 'personal telephone' can be determined as the second level according to the preset privacy degree 'absolute secret' corresponding to the keyword of 'telephone'.

Optionally, when the shared information content is converted into the two-dimensional code, the intelligent terminal may modify the security level or privacy degree corresponding to each type of data in the information content. For example, the smart terminal may use a default view as shown in fig. 3 when converting a business card into a two-dimensional code for the first time. The user can drag an item in the default view, such as pressing the item "QQ" for a long time, to drag "QQ" from "general privacy" to "absolute privacy", so that the intelligent terminal modifies its corresponding privacy level; the 'micro blog' entry can also be dragged from 'general secrecy' to 'no secrecy', so that the intelligent terminal modifies the corresponding privacy degree and modifies the corresponding encryption level of the intelligent terminal at the same time.

Step 202, configuring corresponding target users for the second level.

In the embodiment of the invention, the intelligent terminal can add the trust list in the two-dimensional code, so that a user in the trust list can read the data of the second level in the two-dimensional code, such as the private information and the absolute information in the two-dimensional code. Optionally, the configuring, by the intelligent terminal, the corresponding target user for the second level may specifically include: generating a trust list based on the input contact information, wherein each user in the trust list is a target user; an association between the trust list and the second level is created. Of course, the intelligent terminal may also preset a trust list, so that when the user inputs user information in the shared information content, the corresponding user object is added to the trust list, that is, the user object is set as a target user, so that the user object can read second-level data in the two-dimensional feature data converted from the shared information content.

And 203, performing partition storage on each type of data according to the encryption level to generate a characteristic two-dimensional code corresponding to the target user.

It should be noted that, according to the standard of the two-dimensional code, the data area is usually used as a place where the two-dimensional code stores real data content, and the error correction area is only used for storing an error correction code, so that the intelligent terminal can still read the data content stored in the data area based on the error correction code when the two-dimensional code is polluted and damaged. The two-dimensional code fault tolerance rate can be represented by letters, and the fault tolerance level can be divided into: l (7%), M (15%), Q (25%), H (30%) four stages. Each version of the two-dimensional code is provided with the corresponding maximum number of input characters in combination with the data size, the character type and the error correction level, that is, if the data size is increased, more code elements are needed to form the two-dimensional code, and the two-dimensional code becomes larger.

In the process of generating the two-dimensional code, the private data can be taken as a polluted block, and a part of storage space of the two-dimensional code is occupied. If the embedded private data does not exceed the fault-tolerant range of the two-dimensional code, the integrity of the two-dimensional code data area cannot be affected. Therefore, under the condition of meeting the two-dimensional code standard, the intelligent terminal in the embodiment of the invention can embed information contents such as privacy data and a trust list into the error correction area, so that users who are not in the trust list can only scan the public information in the data area, and the privacy safety of the users is ensured.

Specifically, the intelligent terminal may divide the two-dimensional code into a data area and an error correction area. Wherein the data area can be used for storing public information without security, such as data of a first level; the error correction area may be used to store error correction codes and privacy information, such as a second level of data. Optionally, the partition storage is performed on each type of data according to the encryption level to generate the feature two-dimensional code corresponding to the target user, and the method specifically includes: encrypting the data of the second level and the target user, and storing the encrypted data in an error correction area, for example, encrypting and storing a trust list, the data of the second level, and an association relationship between the trust list and the second level in the error correction area; storing the first level of data in a data area; and synthesizing the error correction area and the data area to generate the characteristic two-dimensional code.

Optionally, the confidential information may have a corresponding expiration time. The expiration time can be used for determining the valid period of the confidential information, so that after the valid period is up, the intelligent terminal invalidates the stored confidential information, for example, deletes the confidential information, thereby further ensuring the security of the confidential information. In a preferred embodiment of the present invention, the information sharing method may further include: configuring corresponding expiration time for the top-secret information; and packaging the expiration time into an error correction area in the generation process of the two-dimensional code. Specifically, the intelligent terminal can configure corresponding expiration time for the absolute secret information in the shared information content according to preset parameter information; or configuring corresponding expiration time for the secret information according to the time information input by the user for the secret information, which is not limited in particular by the embodiment of the present invention.

Fig. 4 is a schematic diagram of a two-dimensional code business card generated by the specific example of the present invention. In the process of generating the two-dimensional code business card, the intelligent terminal can store public information such as names and working phones in the data area, and store private information such as micro signals and microblogs, and absolute information such as private phones and expiration time corresponding to the absolute information, and the trust list in the error correction area, and encrypt the private information and the absolute information, which are stored in the error correction area, only by a target user in the trust list, and synthesize the data area and the error correction area to generate the two-dimensional code business card containing the target user and the expiration time.

In a preferred embodiment of the present invention, the information sharing method may further include: and uploading the trust list to the cloud end, and determining the uniform resource locator of the trust list. The encrypting and storing the trust list in the error correction area may specifically include: storing uniform resource locators for the trust list to the error correction zone.

In the implementation of the invention, in order to store a large amount of data, the intelligent terminal can store the trust list in the characteristic two-dimensional code in the cloud, and encrypt and store the trust list in a Uniform Resource Locator (URL) of the cloud in an error correction area of the two-dimensional code, so that more target users can be configured for the characteristic two-dimensional code under the condition of meeting the standard of the two-dimensional code, that is, the information storage capacity of the two-dimensional code is increased. Certainly, the intelligent terminal may also encrypt and store the URL of the trust list and part of the target users in the trust list in the error correction area, so that in the process of scanning the feature two-dimensional code, under the condition that the corresponding target users cannot be found in the error correction area, the corresponding trust list stored in the cloud is obtained based on the URL of the trust list in the error correction area, and then the target users stored in the cloud are used for verification.

And step 204, sending the characteristic two-dimensional code to a target terminal.

The intelligent terminal provided by the embodiment of the invention can send the characteristic two-dimensional code to the target terminal so as to send the characteristic two-dimensional code to the sharing object, thereby achieving the purpose of information sharing. The target terminal may be determined according to the sharing object, such as an intelligent terminal operated by the sharing object. Specifically, after the characteristic two-dimensional code is generated or acquired by the intelligent terminal, the characteristic two-dimensional code may be sent to the intelligent terminal operated by the sharing object selected by the user, so that the sharing object may acquire the characteristic two-dimensional code.

The embodiment of the invention can add the user to the trust list in a static mode or a dynamic mode so as to set the user as the target user. Specifically, when the user is added to the trust list in a static manner, the intelligent terminal can preset the trust list, so that an object capable of reading the private information in the two-dimensional code can be added to the trust list, the added object is configured as a target user, and a characteristic two-dimensional code containing the target user is generated. Preferably, a trust list corresponding to the readable second-level data is set in a static manner, and the target user in the trust list can be fixed and unchanged all the time after the characteristic two-dimensional code is generated, so that the target user in the trust list can be prevented from being illegally tampered, and the information security is further improved. When the user is added to the trust list in a dynamic mode, the intelligent terminal can add the sharing object to the trust list of the characteristic two-dimensional code, namely, the sharing object is set as the target user of the characteristic two-dimensional code, and therefore the flexibility of adding the target user can be improved.

In a preferred embodiment of the present invention, before sending the characteristic two-dimensional code to the target terminal, the method further includes: verifying whether the current user is an author of the two-dimensional code; and if the current user is the author, adding a sharing object into the trust list, and updating the characteristic two-dimensional code. Wherein, the sending the characteristic two-dimensional code to a target terminal includes: and sending the updated characteristic two-dimensional code to a target terminal. For example, a user A makes a two-dimensional code business card 1 by operating an intelligent terminal and sends the business card 1 to a user B; after receiving the two-dimensional code business card 1, the B can forward the two-dimensional code business card 1 to the C. At this time, the C is not added into the trust list, so that the private data in the two-dimensional code business card 1 cannot be read; and B is in the trust list, so that the private data in the two-dimensional code business card 1 can be read. When A sends the two-dimension code business card to D again, D can also be added into the trust list, namely when A shares D, the intelligent terminal operated by A can read all data of the two-dimension code business card 1, then D is added into the trust list, and a two-dimension code 2 is automatically regenerated to be shared with D. Therefore, the objects shared by the authors of the feature two-dimensional codes can be automatically added to the trust list.

Referring to fig. 5, a schematic flow chart of sending a characteristic two-dimensional code in a specific example of the present invention is shown. Specifically, when the intelligent terminal sets the contents of the business card, the information contents of the business card can be classified into public information, private information and absolute information, then the public information is stored in the data area, the private information, the absolute information and second-level data such as expiration time are stored in the error correction area in an encrypted manner, the characteristic two-dimensional code 1 corresponding to the business card is generated, and therefore information sharing can be performed according to the characteristic two-dimensional code 1. When the feature two-dimensional code is shared, the intelligent terminal can verify whether the current operating user is the author of the feature two-dimensional code 1 or not by acquiring the user information of the current operating user. If the current user is the author of the feature two-dimensional code 1, the sharing object is added into the trust list, the feature two-dimensional code 1 is updated, namely, an updated feature two-dimensional code 2 is generated on the basis of the feature two-dimensional code 1, and then the updated feature two-dimensional code 2 is sent to the target terminal. And if the current user is not the author of the characteristic two-dimensional code, directly sending the characteristic two-dimensional code 1 to the target terminal.

Through the embodiment, even if the characteristic two-dimensional code generated by the intelligent terminal is leaked, the user and/or the intelligent terminal which are not in the trust list of the characteristic two-dimensional code cannot acquire the privacy information in the two-dimensional code under the condition that the encrypted privacy information is not cracked, so that the problem that the privacy information in the characteristic two-dimensional code is leaked can be avoided.

Example two

On the basis of the above embodiment, the two-dimensional code-based scanning process is used to discuss the information sharing method provided by the present invention.

Referring to fig. 6, a flowchart illustrating steps of another embodiment of the information sharing method of the present invention is shown, which may specifically include the following steps:

step 601, scanning the characteristic two-dimensional code.

In the embodiment of the invention, the intelligent terminal can use the camera to scan the characteristic two-dimension; or the characteristic two-dimensional code can be obtained by shooting through a camera, and the obtained characteristic two-dimensional code is scanned to extract the information content stored in the characteristic two-dimensional code from the characteristic two-dimensional code. Of course, the intelligent terminal according to the embodiment of the present invention may also acquire the characteristic two-dimensional code by using the method, for example, the characteristic two-dimensional code is received by using a wireless or wired communication method, which is not limited in this respect.

Wherein, this characteristic two-dimensional code specifically can include: and the two-dimensional code is generated by grading the shared information content and storing each type of data in a partition mode according to the graded encryption level. The encryption levels include a first level and a second level, the first level being lower than the second level, and the second level having a corresponding target user.

Step 602, in the scanning process, data is extracted from the partition corresponding to the first level.

In the feature two-dimensional code of the embodiment of the present invention, the data stored in the partition corresponding to the first level may not be encrypted, and specifically, the method may include: first level data, such as public information that does not need to be kept secret. The intelligent terminal can extract data without encryption, such as data of a first level, from a partition corresponding to the first level of the characteristic two-dimensional code based on a two-dimensional code technology.

Step 603, detecting whether the scanning user is matched with the target user of the characteristic two-dimensional code.

If the scanning user matches the target user, go to step 604; otherwise, the process jumps to step 605.

Specifically, the intelligent terminal can determine the current scanning user by obtaining the user information of the current operation, and further can detect whether the scanning user is matched with the target user of the feature two-dimensional code, so as to check whether the current scanning user has the authority to obtain the data of the second level in the feature two-dimensional code, that is, whether the scanning user belongs to the target user of the feature two-dimensional code. When the scanning user is matched with the target user of the feature two-dimensional code, it can be determined that the scanning user belongs to the target user of the feature two-dimensional code, and then step 604 is executed; when the scanning user does not match with the target user of the feature two-dimensional code, it may be determined that the scanning user does not belong to the target user of the feature two-dimensional code, and the step 605 may be directly skipped to execute.

And step 604, extracting data from the partition corresponding to the second level.

In this step, the intelligent terminal may extract the encrypted and stored data, such as the second-level data in the characteristic two-dimensional code, from the partition corresponding to the second level based on the authority possessed by the target user.

Step 605, the extracted data is saved.

The intelligent terminal can automatically store the data extracted from the characteristic two-dimensional code, so that the stored data can be used in subsequent data processing, corresponding services are provided for users, the requirements of the users are met, and the purpose of information sharing is achieved.

The embodiment of the invention determines whether the scanning user belongs to the target user of the characteristic two-dimensional code by detecting whether the scanning user is matched with the target user of the characteristic two-dimensional code, extracts the data in the subarea corresponding to the second level when the scanning user belongs to the target user of the characteristic two-dimensional code, and only extracts the data in the subarea corresponding to the first level if the scanning user does not belong to the target user of the characteristic two-dimensional code, namely different people can scan different information contents for the same characteristic two-dimensional code, thereby avoiding the embarrassment condition of making different two-dimensional codes for different people and improving the utilization rate of the characteristic two-dimensional code.

Referring to fig. 7, a flowchart illustrating steps of another alternative embodiment of the information sharing method according to the present invention is shown, which may specifically include the following steps:

and step 701, scanning the characteristic two-dimensional code.

In the embodiment of the present invention, the characteristic two-dimensional code may be specifically divided into: a data area and an error correction area. The partition corresponding to the first level may be a data area of the characteristic two-dimensional code, and the partition corresponding to the second level may be an error correction area of the characteristic two-dimensional code.

Step 702, in the scanning process, extracting data of a first level from the data area of the characteristic two-dimensional code.

In the process of reading the two-dimensional code, the intelligent terminal can extract first-level data from a data area of the characteristic two-dimensional code, for example, public information such as 'name', 'hobby' and the like with privacy degree being not required to be kept secret.

Step 703, performing category detection on the data of the first level, and determining a corresponding information category.

After the data of the first level is extracted, the intelligent terminal may determine the information category of the data of the first level according to a preset detection mode, for example, the information category of the characteristic two-dimensional code is determined by detecting a keyword in the data of the first level. For example, when it is detected that the first-level data includes the keyword "name", the information category of the feature two-dimensional code may be determined as business card information.

Step 704, determining the corresponding target database by using the information type.

Wherein the target database is used for storing the extracted data. For example, in combination with the above example, the intelligent terminal may use a business card database corresponding to the business card information as a target database to store the extracted data in the business card database.

Step 705, detecting whether the scanning user is matched with the target user of the characteristic two-dimensional code.

If the scanning user matches the target user, go to step 706; otherwise, go to step 707 and execute.

Step 706, extracting the data of the second level from the error correction area of the characteristic two-dimensional code.

In this step, the intelligent terminal may extract, according to the authority of the target user, data of a second level, such as private information with a privacy degree of "general secrecy" and absolute information with a privacy degree of "absolute" from the error correction area of the feature two-dimensional code.

Step 707, store the extracted data into the target data.

The extracted data in this embodiment includes data of a first level, and may also include data of a second level. Therefore, saving the extracted data may specifically include: and storing the data of the first level and the data of the second level to the target database.

In a preferred embodiment of the present invention, the second level data may specifically include: private information and confidential information, where the confidential information may have a corresponding expiration time. When the intelligent terminal stores the extracted data, the private information can be stored in a plaintext mode; the effectiveness of the top-secret information can be determined by judging whether the current time exceeds the expiration time, and when the current time exceeds the expiration time, the intelligent terminal can determine that the top-secret information is expired and delete the top-secret information; and when the current time does not exceed the expiration time, determining that the secret information is not expired, and storing the secret information in a ciphertext mode. When the intelligent terminal stores the top secret information, the validity of the top secret information in the characteristic two-dimensional code can be detected through the expiration time in the characteristic two-dimensional code, so that the expired top secret information can be automatically deleted, the unexpired top secret information can be stored in a ciphertext mode, and the information safety is further improved.

Optionally, after determining that the top secret information is not expired, the intelligent terminal may further determine valid time corresponding to the top secret information by using the expiration time, and may store the valid time in the target database, so that when the top secret information is used, the validity of the top secret information may be detected by using the valid time. Specifically, after storing the extracted data, the intelligent terminal may detect whether the secret information is valid by using the valid time when the application calls the secret information. When the secret-insulated information is effective, the intelligent terminal can decrypt the secret-insulated information to generate corresponding plaintext data and feed the plaintext data back to the application program, so that the application program can use the plaintext data to provide services for the user.

After feeding back plaintext data to the application program, the intelligent terminal of the embodiment of the invention can also display the first-level data corresponding to the secret information. Specifically, when using the two-dimensional code data stored in the target database, the smart terminal may determine whether a producer of the two-dimensional code wishes the data to be disseminated by determining whether the privacy level corresponding to the data is absolute. If the data corresponds to an absolute degree of privacy, it can be determined that the producer of the two-dimensional code does not want the data to be propagated. For example, author a of a two-dimensional code shares a phone number with salesperson B, but a does not want B to share the number to other salespersons, nor does B know his number all the time. At this time, the privacy degree corresponding to the telephone number of the A can be set to be top secret, so that when the telephone number of the A is displayed in the smart phone, the telephone number of the A can be displayed in a ciphertext mode instead of a plaintext mode, for example, the number of the A is not displayed, the telephone number of the A can not be known by the B, and the telephone number of the A can not be disclosed by the B.

As a specific example of the present invention, the smart phone may encrypt and display the confidential information. Since the system of the smart phone knows the encryption method, when the secret information is used for operation in the system, the smart phone can decrypt the secret information into plaintext data and then use the plaintext data. Specifically, in the storage process of the smart phone, the extracted data can be stored in the business card database according to the classification of information privacy in the two-dimensional code business card, and the storage format of the data can be as shown in table 1:

name of field	Field value	Degree of privacy
			Name (I)	Mr.k	Disclosed is a
QQ	12345	In general
			Telephone set	12321	Absolute secret

TABLE 1

The encrypted phone number can be stored in the smart phone in a ciphertext mode, and a phone program of the smart phone can obtain a real number through reverse operation.

Of course, the real number may also be stored in the smartphone in clear text. If the privacy degree corresponding to the real number is the top secret, the phone program of the smart phone can be dialed by using the real number, but the real number is not displayed, namely, the information itself is not displayed, so that the user can be prevented from acquiring the information when using the stored top secret information, and the top secret information can be prevented from being leaked by the user. Therefore, when the user shares the name card with the salesperson, the salesperson does not need to worry about the leakage of personal information of the salesperson, and the situation that the salesperson receives a sales call endlessly can be avoided.

The method and the device are not limited to application scenes for sharing business cards, and can also be applied to application scenes for sharing other information, such as application scenes for sharing web addresses, video and video. The implementation of the invention can meet the requirement of grading information according to the privacy degree of the information when sharing the information, and can realize directional sharing by setting the target user, thereby improving the flexibility of information sharing.

It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
