Detailed Description

For a person skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. The embodiments in the present application shall fall within the protection scope of the present application.

The following describes in detail an encryption method for AR data disclosed in an embodiment of the present application.

Fig. 1 is a schematic flowchart of an encryption method for AR data according to an embodiment of the present application. The method may be applied to an electronic device, which may include, for example, a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a Personal Digital Assistant (PDA), a wearable device (such as a watch, a wrist, glasses, a helmet, a headband, and the like), a server, and the like, and the specific form of the electronic device is not particularly limited in the embodiments of the present application.

As shown in fig. 1, the method may include:

101. and acquiring the book identification of the book to which the AR data belongs and the drawing identification of the AR data in the book to which the AR data belongs.

It is understood that both the book and outline identifiers may be represented in the form of a sequence.

In this embodiment of the present application, the process of acquiring the AR data may include: when the point reading equipment detects that the point reading operation exists on the point reading equipment, the point reading equipment acquires the content to be read according to the point reading operation and sends the content to be read to the electronic equipment. Thus, the electronic device can obtain the AR data corresponding to the content to be read.

Further, in order to improve the accuracy of content matching, acquiring the content to be read according to the read-on operation may include: and acquiring the content to be read, a plurality of upper contents of the content to be read and a plurality of lower contents of the content to be read according to the reading operation.

The book identification of the book to which the AR data belongs and the delineation identification of the AR data in the book to which the AR data belongs may be obtained by, but not limited to, the following manners:

in the first mode, the electronic device may pre-establish an identifier correspondence relationship between the candidate AR data, the book identifier of the book to which the candidate AR data belongs, and the delineation identifier of the candidate AR data in the book to which the candidate AR data belongs. Therefore, the electronic equipment can acquire the book identification of the book to which the AR data belongs and the delineation identification of the AR data in the book to which the AR data belongs according to the identification corresponding relation.

And secondly, the electronic equipment can perform content matching according to the contents to be read to obtain book identifications of the books to which the contents to be read belong and delineation identifications of the contents to be read in the books to which the contents to be read belong. Therefore, the book identification of the book to which the content to be read by pointing belongs can be used as the book identification of the book to which the AR data belongs, and the drawing identification of the content to be read by pointing in the book to which the content belongs can be used as the drawing identification of the AR data in the book to which the content belongs.

It can be understood that the electronic device may store a plurality of book scanning pages included in the book in advance, so that the book scanning pages and the contents to be read may be used to perform content matching, so as to obtain the book identifier of the book to which the contents to be read belong and the delineation identifier of the contents to be read in the book to which the contents to be read belong.

In alternative embodiments of the present application, a book may be provided with a delineation mark by, but not limited to, the following means:

the method comprises the steps of dividing a book into a plurality of delineation areas from a first page to a last page, and setting delineation marks in each delineation area.

For example, if a book is divided into 205 delineating areas from the first page to the last page, the delineating identifiers corresponding to the 205 delineating areas may be sequentially set as: draw1, draw2, …, and draw 205.

In a second mode, the method can divide a target page included in one book into a plurality of delineation areas, and set delineation marks for the plurality of delineation areas respectively; the target page is any page of the book.

For example, if the first page of a book is divided into 5 delineation areas, the delineation marks corresponding to the 5 delineation areas may be sequentially set as: draw1, draw2, draw3, draw4, draw 5; if the first page of a book is divided into 16 delineating areas, the delineating identifications corresponding to the 16 delineating areas can be sequentially set as: draw1, draw2, …, draw15, and draw 16.

It should be noted that, if the delineation flag is set by the method described in the second mode, step 101 may be replaced by: and acquiring a book identifier of the book to which the AR data belongs, a drawing identifier of the AR data in the book to which the AR data belongs, and a page identifier of the AR data in the book to which the AR data belongs. Therefore, in the subsequent steps, the data identification sequence of the AR data can be obtained according to the book identification, the delineation identification and the page number identification, so that the obtained data identification sequence has uniqueness.

102. And acquiring a data identification sequence of the AR data according to the book identification and the delineation identification.

The data identification sequence of the AR data may be obtained by, but is not limited to, the following ways:

in the first mode, the electronic device can combine the book mark and the delineation mark to obtain a data mark sequence of the AR data.

Further, the electronic device may combine the book identifier and the delineation identifier according to a first preset priority to obtain a data identifier sequence of the AR data, where the first preset priority includes an arrangement order between the book identifier and the delineation identifier.

For example, if the priority of the book identifier is higher than that of the delineation identifier, the book identifier may be used as a front part sequence in the data identifier sequence, and the delineation identifier may be used as a rear part sequence in the data identifier sequence. For example, a book is identified as: x₁X₂X₃…X_nThe delineation mark is: y is₁Y₂Y₃…Y_mM and n are positive integers, in this case, the data identification sequence can beComprises the following steps: x₁X₂X₃…X_nY₁Y₂Y₃…Y_m。

And secondly, the electronic equipment can combine the book identification, the drawing identification and the designated identification to obtain a data identification sequence of the AR data. The specified identifier may be at least one of a device identifier of the reading device and a date identifier of the current date.

At this time, the sending, by the reading device described in step 101, the content to be read to the electronic device may include: and the point reading equipment sends the content to be point read and the equipment identification of the point reading equipment to the electronic equipment.

Further, the electronic device may combine the book identifier, the delineation identifier, and the specific identifier according to a second preset priority to obtain a data identifier sequence of the AR data, where the second preset priority includes an arrangement order among the book identifier, the delineation identifier, and the specific identifier.

For example, if the specified identifier includes a device identifier of the reading device and a date identifier of the current date, and the second preset priority may include: the priority of the book identification > the priority of the delineation identification > the priority of the device identification > the priority of the date identification. The sequence of data identifications may include, in order, a book identification, a delineation identification, a device identification, and a date identification. For example, a book is identified as: x₁X₂X₃…X_nThe delineation mark is: y is₁Y₂Y₃…Y_mThe equipment identifier is Z₁Z₂Z₃…Z_iThe date identifier is 20200514, and m, n, i are positive integers, in this case, the data identifier sequence may be: x₁X₂X₃…X_nY₁Y₂Y₃…Y_mZ₁Z₂Z₃…Z_i20200514。

And thirdly, if the page identifier of the AR data in the book in the step 101 needs to be acquired, the electronic device may combine the book identifier, the sketching identifier and the page identifier to obtain a data identifier sequence of the AR data.

Further, the electronic device may combine the book identifier, the delineation identifier, and the page identifier according to a third preset priority to obtain a data identifier sequence of the AR data, where the third preset priority includes an arrangement order among the book identifier, the delineation identifier, and the page identifier.

For example, if the third predetermined priority may include: the priority of book mark > the priority of outline mark > the priority of page number mark. The data identification sequence may comprise book identification, outline identification, page identification in sequence. For example, a book is identified as: x₁X₂X₃…X_nThe delineation mark is: y is₁Y₂Y₃…Y_mPage number marked as Q₁Q₂Q₃…Q_jAnd m, n and j are positive integers, and in this case, the data identification sequence may be: x₁X₂X₃…X_nY₁Y₂Y₃…Y_mQ₁Q₂Q₃…Q_j。

Further, the method and the device can also combine the book identification, the delineation identification, the designated identification and the page number identification to obtain a data identification sequence of the AR data. For the specific process, reference may be made to the above contents, which are not described herein again.

In an optional embodiment of the present application, the electronic device may preset a designated identification digit corresponding to the target identification (equivalent to the book identification, the outline identification, the designated identification, and the page identification). Therefore, under the condition that the identification digit of the target identification is not the designated identification digit, identification adjustment can be carried out on the target identification, so that the step can obtain the data identification sequence of the AR data according to the adjusted target identification. Therefore, through the identification adjustment process, the data identification sequences corresponding to different AR data have the same sequence length, so that the data management is convenient to unify, and the encrypted data is convenient to decrypt.

It is to be understood that the identity adjustment of the target identity may include:

and deleting the appointed sub-identification included in the target identification under the condition that the identification digit number of the target identification is greater than the appointed identification digit number, wherein the identification digit number of the appointed sub-identification is the difference value between the identification digit number of the target identification and the appointed identification digit number. Alternatively, the designated sub-identifier may be the identifier of the last part of the target identifier.

And under the condition that the identification digit number of the target identification is smaller than the designated identification digit number, adding a designated number of preset values into the target identification, wherein the designated number is a difference value between the designated identification digit number and the identification digit number of the target identification, and the preset values can be manually predetermined numerical values. Alternatively, the preset value may be added to the rear of the target identifier, or may be added to the front of the target identifier. The preset value may be a positive integer. The above examples are merely illustrative, and the present application is not limited thereto.

103. And acquiring a target binary value corresponding to the AR data.

In this embodiment of the application, a target binary value corresponding to the AR data may be obtained according to a preset data conversion relationship.

Alternatively, the AR data includes characters each having a corresponding ASCII (American standard code for Information Interchange) code value. Thus, the ASCII encoded value may be converted to a specified type value (e.g., int type value) which is then converted to the target binary value. The above examples are merely illustrative, and the present application is not limited thereto.

It should be noted that, the present application does not limit the timing sequence of step 103, for example, step 103 may precede step 101, or precede step 102.

104. And acquiring encrypted data corresponding to the AR data according to the target second-level system numerical value and the data identification sequence.

In the embodiment of the application, the electronic device can obtain a target numerical value corresponding to the designated bit according to the data identification sequence; acquiring a binary number value to be calculated corresponding to the AR data according to the target value; and then, carrying out operation processing on the binary numerical value to be operated and the target secondary system numerical value to obtain encrypted data corresponding to the AR data.

It is understood that obtaining the target value corresponding to the designated bit according to the data identification sequence may include: under the condition that the target designated bit exists in the data identification sequence, acquiring a numerical value corresponding to the target designated bit in the data identification sequence to obtain a target numerical value corresponding to the target designated bit; under the condition that the target designated bit does not exist in the data identification sequence, taking a preset value as a target value corresponding to the target designated bit; wherein the designated bits include target designated bits. For example, the preset value may be a positive integer.

Illustratively, if the data identification sequence includes: x₁X₂X₃X₄Y₁Y₂Y₃Y₄Y₅Q₁Q₂Q₃If the preset number is 9, then if the designated bit includes the first bit and the sixth bit, since the first bit and the sixth bit exist in the data id sequence, it can be obtained: the first bit corresponds to a target value of X₁The sixth bit corresponds to a target value of Y₂(ii) a In the case where the designated bits include the first bit, the sixth bit, and the fifteenth bit, since the first bit and the sixth bit exist in the data identification sequence, and the fifteenth bit does not exist, it is possible to obtain: the first bit corresponds to a target value of X₁The sixth bit corresponds to a target value of Y₂And the fifteenth bit corresponds to a target value of 9.

Further, the designated bits may include an f-th bit, f + k₁Bit, f + k₂Bit …, f + k_vBit, f, k_vAll represent positive integers.

Alternatively, k₂、…、k_vCan be k₁Multiples of (a).

Optionally, to improve the data security, if the f bit, the f + k bit₁Bit, f + k₂Bit …, f + k_vThe target value of at least one of the bits is 0. Then 0 in the target value can be removed, so that the binary value to be operated corresponding to the AR data can be obtained according to the target value from which 0 is removed. Thus, the binary value to be calculated acquired subsequently is ensured not to be changedIs 0, so that the security of the encrypted data obtained by subsequently encrypting the AR data is higher.

Alternatively, according to the setting rule of the data identification sequence, a plurality of bits with historical numerical values different from 0 can be used as the designated bits.

In this way, obtaining the binary value to be calculated corresponding to the AR data according to the target value may include, but is not limited to, the following manners:

in the first mode, under the condition that the designated bits comprise at least two bits, the product between the target numerical values corresponding to each target designated bit is calculated, and the binary numerical value to be calculated corresponding to the AR data is obtained.

For example, if the designated bits include the p-th bit and the p + s-th bit, p is a natural number and s is a positive integer. Under the condition that the p-th bit and the p + s-th bit exist in the data identification sequence, calculating the product between the target value corresponding to the p-th bit and the target value corresponding to the p + s-th bit to obtain a binary value to be calculated corresponding to the AR data; under the condition that the p-th bit exists in the data identification sequence but the p + s-th bit does not exist, the target value corresponding to the p + s-th bit can be determined to be a preset value, and the product between the target value corresponding to the p-th bit and the preset value is calculated to obtain the binary value to be calculated corresponding to the AR data.

For another example, if the designated bits include the p-th bit, the p + s-th bit, and the p + r-th bit, p is a natural number, and s and r are positive integers. Under the condition that the p bit, the p + s bit and the p + r bit exist in the data identification sequence, calculating the product of the target value corresponding to the p bit, the target value corresponding to the p + s bit and the target value corresponding to the p + r bit to obtain a binary value to be calculated corresponding to the AR data; under the condition that the p-th bit and the p + s-th bit exist in the data identification sequence but the p + r-th bit does not exist, the target value corresponding to the p + r-th bit can be determined to be a preset value, and the product of the target value corresponding to the p-th bit, the target value corresponding to the p + s-th bit and the preset value is calculated to obtain a binary value to be calculated corresponding to the AR data. The above examples are merely illustrative, and the present application is not limited thereto.

If the application determines the to-be-operated secondary system numerical value by the method of the first mode, performing operation processing on the to-be-operated binary value and the target secondary system numerical value to obtain the encrypted data corresponding to the AR data, which may include:

carrying out XOR operation on the binary number to be operated and the target secondary system numerical value to obtain encrypted data corresponding to the AR data; alternatively, the first and second electrodes may be,

carrying out exclusive OR operation on the binary number value to be operated and the target secondary system numerical value to obtain encrypted data corresponding to the AR data; alternatively, the first and second electrodes may be,

carrying out AND-OR operation on the binary numerical value to be operated and the target secondary system numerical value to obtain encrypted data corresponding to the AR data; alternatively, the first and second electrodes may be,

carrying out NAND operation on the binary number value to be operated and the target secondary system numerical value to obtain encrypted data corresponding to the AR data; alternatively, the first and second electrodes may be,

and performing NOR operation on the binary number value to be operated and the target second-level system numerical value to obtain the encrypted data corresponding to the AR data.

Optionally, performing operation processing on the binary number value to be operated and the target secondary system numerical value to obtain an initial operation result, and acquiring encrypted data corresponding to the AR data from the initial operation result; the data bit number of the encrypted data is the same as the numerical bit number of the target second-level system value. And if the numerical digit of the target secondary system numerical value is less than the numerical digit of the binary numerical value to be operated, the encrypted data is the data behind the initial operation result. The above-mentioned operation processing method is only an exemplary one, and the present application does not limit this.

In a second manner, under the condition that the designated bits include at least three bits, obtaining a binary value to be calculated corresponding to the AR data according to the target value may include: acquiring at least two predetermined bit combinations; the bit combination comprises at least two bits of the designated bits; then, calculating the product of the target numerical values corresponding to at least two bits included in each bit combination to obtain a binary numerical value to be calculated of each bit combination; the binary value to be calculated corresponding to the AR data includes a binary value to be calculated of at least two bit combinations. Wherein the two different bit combinations may include the same bit.

For example, assume that the designated bits include the p-th bit, the p + s-th bit, and the p + r-th bit, p is a natural number, and s and r are positive integers; the data identification sequence has the p th bit and the p + s th bit, but does not have the p + r th bit, and the target value corresponding to the p + r th bit can be determined to be a preset value. If the predetermined at least two bit combinations include: a first combination of the p-th bit and the p + s-th bit, a second combination of the p + s-th bit and the p + r-th bit, and a third combination of the p-th bit and the p + r-th bit. Then, the product of the target values respectively corresponding to the p-th bit and the p + s-th bit included in the first combination can be obtained to obtain a first binary value to be operated; obtaining the product of target values respectively corresponding to the p + s th bit and the p + r th bit included in the second combination to obtain a second binary value to be operated; and obtaining the product of target numerical values respectively corresponding to the p-th bit and the p + r-th bit included in the third combination to obtain a third binary numerical value to be calculated.

If the to-be-operated two-level system value of at least two bit combinations is obtained by the method described in mode two, in an optional embodiment, the performing operation processing on the to-be-operated binary value and the target two-level system value to obtain the encrypted data corresponding to the AR data may include: respectively carrying out primary operation processing on the binary value to be operated of each bit combination and a target secondary system value to obtain initial encrypted data; and carrying out second operation processing on the initial encrypted data to obtain encrypted data corresponding to the AR data.

It is understood that the first operation processing may include one of exclusive or operation processing, and or nor operation processing, nand operation processing, nor operation processing, and the like.

It should be understood that since there are at least two pieces of initial encrypted data acquired in the present application, a second arithmetic processing is required. Further, under the condition that at least three pieces of initial encrypted data are obtained, a second operation processing may be performed on two target initial encrypted data of the at least three pieces of initial encrypted data to obtain a processing result, and a second operation processing may be performed according to the processing result and the first remaining initial encrypted data to obtain encrypted data corresponding to the AR data; the first remaining initial encrypted data is initial encrypted data of the at least three initial encrypted data excluding the two target initial encrypted data.

Further, if at least two first remaining initial encrypted data are obtained, performing a second operation process according to the processing result and the first remaining initial encrypted data to obtain encrypted data corresponding to the AR data, which may include: and performing second operation processing on the processing result and one target residual initial encrypted data in the first residual initial encrypted data to obtain a new processing result, and performing second operation processing on the new processing result and the second residual initial encrypted data to obtain encrypted data corresponding to the AR data, wherein the second residual initial encrypted data is the initial encrypted data except the one target residual initial encrypted data in the first residual initial encrypted data.

The second arithmetic processing may include one of exclusive or arithmetic processing, and or nor arithmetic processing, nand arithmetic processing, nor arithmetic processing, and the like.

Illustratively, if the number of the obtained initial encrypted data is 3, the obtained initial encrypted data includes first initial encrypted data, second initial encrypted data, and third initial encrypted data. In this step, the first initial encrypted data and the second initial encrypted data may be subjected to xor operation to obtain a processing result, and the processing result and the third initial encrypted data may be subjected to xor operation to obtain encrypted data corresponding to the AR data.

It should be noted that, after the encrypted data corresponding to the AR data is obtained, the encrypted data may be sent to the point-to-read device. Thus, the probability of being tampered during data transmission is reduced.

According to the AR data encryption method, because the AR data has a mapping relation with the book identification and the delineation identification of the AR data in the book, the data identification sequence obtained according to the book identification and the delineation identification is the unique identification of the AR data.

201. and the point reading equipment acquires the content to be point read under the condition of detecting the point reading operation.

In the embodiment of the present application, the content to be read may be obtained by, but is not limited to, the following ways:

in a first mode, the touch and talk operation may be a designated gesture on a display screen of the touch and talk device. Therefore, the point-reading equipment can detect whether the appointed gesture exists on the display screen of the point-reading equipment, and if the appointed gesture exists on the display screen of the point-reading equipment, the contents to be point-read indicated by the appointed gesture are collected. The designated gesture may be a pointing gesture of a single finger, or may also be a pointing gesture of two fingers, and the like, which is not limited in this application.

And secondly, the point reading operation can be a trigger operation of a point reader (such as a point reading pen and the like) on a display screen of the point reading device, and the like. Wherein, the point reader and the point reading device can be bound in advance. Therefore, the point reading device can detect whether the point reader exists on the display screen of the point reading device, and if the appointed point reader exists on the display screen of the point reading device, the content to be read indicated by the point reader is collected.

And thirdly, the point reading operation can be a virtual sketching track on a display screen of the point reading equipment. Therefore, the point-reading device can detect whether the display screen of the point-reading device has the virtual delineation track or not, and if the display screen of the point-reading device has the virtual delineation track, the point-reading content indicated by the virtual delineation track is acquired. For example, the virtual delineation track may be a primitive track or a rectangular track, etc.

In the fourth mode, the click-to-read operation can be a click-to-read voice command. Therefore, the point-reading device detects whether the user inputs the point-reading voice instruction, and if the point-reading device detects that the user inputs the point-reading voice instruction, the contents to be point-read on the display screen of the point-reading device can be acquired according to the point-reading voice instruction. The click-to-read voice instruction may include content position information of the content to be clicked and read. For example, the content position information may be row information and column information corresponding to the content to be read.

It is to be understood that the point-reading device may be a point-reading machine, and the like, and the present application is not limited thereto.

202. And the point reading equipment sends the content to be read to the electronic equipment.

203. The electronic equipment acquires AR data corresponding to the content to be read under the condition that the content to be read is received.

204. The electronic device determines whether the AR data is target data.

It is understood that the electronic device may preset the degree of importance of the candidate AR data.

Wherein the importance of the candidate AR data may be set manually in the electronic device. Thus, the target data may be data having a degree of importance equal to or greater than a preset degree threshold. Alternatively, the longer the production time of the candidate AR data, the greater the degree of importance.

Of course, the electronic device may also determine whether key information (e.g., information such as an identification number and a bank card number) exists in the candidate AR data, and if so, determine that the AR data is the target data; and if not, determining that the AR data is not the target data.

If the AR data is the target data, step 205 to step 208 are performed;

in the case where the AR data is not the target data, step 209 is executed.

205. The electronic equipment acquires the book identification of the book to which the AR data belongs and the drawing identification of the AR data in the book to which the AR data belongs.

207. The electronic equipment acquires a target binary value corresponding to the AR data.

208. The electronic equipment acquires the encrypted data corresponding to the AR data according to the target secondary system value and the data identification sequence, and sends the encrypted data to the reading equipment so that the reading equipment can output the encrypted data.

The content of step 205 to step 208 may refer to the content of step 101 to step 104, which is not described herein again.

Therefore, for important AR data, the electronic device needs to be encrypted, so that important information is prevented from being leaked.

It can be understood that, if the reading-and-clicking device is connected with the wearable device and the reading-and-clicking device detects that the wearable device is worn by the user, the reading-and-clicking device can control a camera on the wearable device to output the encrypted data. Wherein, the wearable device can be AR glasses, a smart watch or a smart ring, etc. This allows the encrypted data to be output in different ways.

It should be understood that outputting the encrypted data by the point-to-read device may include: the point-reading device decrypts the encrypted data to obtain decrypted AR data, and accordingly the decrypted AR data are output.

209. The electronic device sends the AR data to the reading device so that the reading device outputs the AR data.

It can be understood that, if the reading device is connected with the wearable device and the reading device detects that the wearable device is worn by the user, the reading device may control the camera on the wearable device to output the AR data. Wherein, the wearable device can be AR glasses, a smart watch or a smart ring, etc. This allows the AR data to be output in different ways.

According to the AR data encryption method, because the AR data has a mapping relation with the book identification and the delineation identification of the AR data in the book, when the AR data is important data, the data identification sequence obtained according to the book identification and the delineation identification is the unique identification of the AR data. Therefore, the data encryption is carried out on the target binary numerical value corresponding to the important AR data through the unique identifier, so that the security of the important data can be ensured, and the encryption efficiency is improved.

In another optional embodiment of the present application, in a case that the current bandwidth resource occupancy rate is less than a preset occupancy threshold, the electronic device obtains a transmission data amount of the encrypted data, and if the transmission data amount is less than or equal to the preset data amount, step 310 is executed; if the transmission data volume is greater than the preset data volume, the data transmission consumes a long time and occupies a large bandwidth resource, so that the electronic device needs to perform data compression on the encrypted data and send the encrypted data after data compression to the point reading device. Therefore, after receiving the encrypted data after data compression, the point reading device needs to decompress the encrypted data after data compression to obtain the encrypted data.

309. The electronic device waits for a preset duration and returns to step 308.

For example, the preset time period may be 2 seconds, 3 seconds, or the like.

310. The electronic device sends the encrypted data to the reading device so that the reading device outputs the encrypted data.

It can be understood that, if the reading-and-clicking device is connected with the wearable device and the reading-and-clicking device detects that the wearable device is worn by the user, the reading-and-clicking device can control a camera on the wearable device to output the encrypted data. Wherein, the wearable device can be AR glasses, a smart watch or a smart ring, etc.

According to the AR data encryption method, because the AR data has a mapping relation with the book identification and the delineation identification of the AR data in the book, the data identification sequence obtained according to the book identification and the delineation identification is the unique identification of the AR data. Therefore, the data encryption is carried out on the target binary number value corresponding to the AR data through the unique identifier, so that the encryption efficiency is improved while the safety of important data is ensured. In addition, in order to avoid the problem that the electronic equipment is down due to high occupation of the bandwidth resources of the electronic equipment, the encrypted data can be transmitted when the occupation of the bandwidth resources of the electronic equipment is not high.

410. And the point-reading equipment detects whether the current position information has corresponding historical playing volume.

It will be appreciated that the playback volume used by the user is different in different location areas. For example, at home, the user prefers a lower playback volume; in a classroom, users prefer a larger playback volume, and so on.

Optionally, in this step, a target position area to which the current position information belongs may be obtained, and it is determined whether there is a historical playing volume in the target position area, and if so, there is a corresponding historical playing volume in the current position information; and if not, the current position information does not have the corresponding historical playing volume.

in the case where the current position information does not have a corresponding history play volume, step 412 is performed.

411. The point-reading equipment determines the target playing volume according to the historical playing volume and outputs the encrypted data according to the target playing volume.

It is to be understood that this step may determine the target playback volume based on the historical playback volume. For example, the average value of the history playback volume may be determined as the target playback volume.

In another alternative embodiment, the playing volume used by the user is different in each time period in the same location area. Therefore, the target position area to which the current position information belongs and the target time period to which the current time belongs can be further acquired, the historical playing volume in the target position area and the target time period can be acquired, and then the target playing volume can be determined according to the historical playing volume. For example, an average of the historical playback volumes may be determined to result in a target playback volume.
