The present invention is described in further detail below with reference to the attached drawing figures.

Fig. 1 shows a schematic configuration of an apparatus for encrypting/decrypting text in an input method according to an aspect of the present invention.

The apparatus 1 is located, for example, in a computer device, comprising acquisition means 101, processing means 102 and providing means 103. Specifically, the obtaining device 101 obtains a character to be encrypted/decrypted, which is input by a user in an input box of an input method; the processing device 102 performs corresponding encryption/decryption processing on the characters to be encrypted/decrypted based on the encryption/decryption operation of the user on the input panel corresponding to the input method, so as to obtain encrypted/decrypted characters; the providing device 103 provides the encrypted/decrypted text to the user in the input box of the input method.

The obtaining device 101 obtains the text to be encrypted/decrypted, which is input by the user in the input box of the input method.

Specifically, a user inputs a text to be encrypted/decrypted in an input box of an input method of the user equipment through interaction with the user equipment, and the obtaining device 101 obtains the text to be encrypted/decrypted, which is input by the user in the input box of the input method, for example, by calling an Application Program Interface (API) or other appointed communication methods provided by the user equipment one or more times.

Here, the user may be a sending user who needs to encrypt the text, or may be a receiving user who needs to decrypt the text, and the way in which the user inputs the text to be encrypted/decrypted into the input box of the input method includes, but is not limited to, typing in, copy and paste, or even voice input. For example, a sending user inputs a to-be-encrypted character in an input frame of an input method by typing and the like, the device 1 encrypts the to-be-encrypted character, and then the sending user sends the encrypted character to a corresponding receiving user; the receiving user obtains the encrypted character, that is, the encrypted character is used as a character to be decrypted, and the character is input into an input box of the input method through modes such as copying and pasting, and the device 1 can perform corresponding decryption processing on the character to be decrypted.

It should be understood by those skilled in the art that the above-mentioned method for obtaining the text to be encrypted/decrypted by the user is only an example, and other existing or future methods for obtaining the text to be encrypted/decrypted by the user, such as applicable to the present invention, are also included in the scope of the present invention and are hereby incorporated by reference.

The processing device 102 performs corresponding encryption/decryption processing on the text to be encrypted/decrypted based on the encryption/decryption operation of the user on the input panel corresponding to the input method, so as to obtain the encrypted/decrypted text.

Specifically, after the user inputs the text to be encrypted/decrypted into the input box of the input method, the user performs an encryption/decryption operation on the input panel by, for example, clicking a specific button, and the processing device 102 performs a corresponding encryption/decryption process on the text to be encrypted/decrypted based on the encryption/decryption operation of the user, for example, performs a corresponding encryption/decryption process on the text to be encrypted/decrypted by using technologies such as a symmetric key and an asymmetric key, so as to obtain the encrypted/decrypted text.

Here, the input panel may have, for example, an "encryption button" and a "decryption button" corresponding to each other, and when the user clicks the encryption button, the processing device 102 performs a corresponding encryption operation on the text to be encrypted, and when the user clicks the decryption button, the processing device 102 performs a corresponding decryption operation on the text to be decrypted, and preferably, the encryption button and the decryption button may also be the same button, for example.

In a preferred embodiment, the processing device 102 performs corresponding encryption/decryption operations for the text to be encrypted/decrypted of the user, for example, through a password library. For example, a character string is stored in the password library, when a user needs to encrypt a character to be encrypted (an original character), the processing device 102 selects a character string from the password library for the character to be encrypted, uses the character string as a character after the character to be encrypted is encrypted, and establishes a temporary mapping relationship between the character to be encrypted and the character string, when a receiving user receives the encrypted character, that is, the character string, uses the character string as a character to be decrypted and performs decryption, and the processing device 102 finds a corresponding original character from the password library according to the character string and the temporary mapping relationship, uses the original character as a decrypted character, and provides the decrypted character to the receiving user. Preferably, the character string stored in the password library may be a character string having semantic logic, such as "i eat roasted meat meal today", "weather is good today", etc., so that even if the chat conversation between the sending user and the receiving user is seen by others, the piece of chat information is not known to be encrypted.

It should be understood by those skilled in the art that the above-mentioned manner for performing corresponding encryption/decryption processing on the text to be encrypted/decrypted is only an example, and other manners for performing corresponding encryption/decryption processing on the text to be encrypted/decrypted, which may exist or may appear in the future, such as applicable to the present invention, should also be included in the scope of the present invention, and are hereby incorporated by reference.

The providing device 103 provides the encrypted/decrypted text to the user in the input box of the input method.

Specifically, the providing device 103 provides the encrypted/decrypted characters to the user in the input box of the input method according to the encrypted/decrypted characters obtained by the processing device 102, so that the user can perform subsequent operations, for example, the user can click a send button to send the encrypted characters, or delete the decrypted characters in the input box, thereby inputting other characters that the user wants to input. When the user clicks the encryption/decryption button on the input panel of the input method, the characters to be encrypted/decrypted in the input frame of the input method can be converted into the encrypted/decrypted characters.

It should be understood by those skilled in the art that the above-mentioned manner of providing encrypted/decrypted text is merely exemplary, and other manners of providing encrypted/decrypted text that may exist or may come within the future, such as may be suitable for use with the present invention, are intended to be included within the scope of the present invention and are hereby incorporated by reference.

The sending user who sends the information can encrypt the original information of the sending user, the device 1 converts the original information into a text irrelevant to the original information, and the receiving user who receives the information can see the original information only after decoding the information, so that the chatting information cannot be leaked even if the mobile phone and other equipment of the user fall into other people or the information is seen by other people, the personal privacy of the user is greatly protected, and the use experience of the user is improved.

Preferably, the user is a sending user who needs ciphertext, wherein the apparatus 1 further comprises sending means (not shown). The sending device sends the encrypted characters to corresponding receiving users based on sending operation of the sending users on the encrypted characters.

Specifically, if the user is a sending user who needs to encrypt a text, the sending user types and inputs a text to be encrypted in an input box of an input method of the user equipment through a physical keyboard, a virtual keyboard and the like through interaction with the user equipment, and the obtaining device 101 obtains the text to be encrypted, which is input in the input box of the input method by the sending user, for example, by calling an Application Program Interface (API) provided by the user equipment or other appointed communication manners one or more times; subsequently, the processing device 102 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method, so as to obtain encrypted text; the providing device 103 provides the encrypted text to the user in an input box of the input method; next, the transmitting user performs a transmission operation on the encrypted character by, for example, clicking a transmission button, and the transmitting apparatus transmits the encrypted character to the corresponding receiving user based on the transmission operation of the transmitting user.

More preferably, the processing device 102 performs corresponding encryption processing on the text to be encrypted based on an encryption operation of the sending user on an input panel corresponding to the input method and in combination with the aging information of the encryption operation, so as to obtain the encrypted text.

Specifically, the encryption operation may have certain aging information, and the processing device 102 may add the aging information of the encryption operation to a specific field of the encrypted text when the text to be encrypted is encrypted. The time information may be, for example, only time information indicating a specific time at which the sending user clicks a specific button on an input panel of the input method to perform an encryption operation; or a time period threshold information, which may specify that the encrypted text is valid to be decrypted within a time period threshold, for example, within 5 minutes, when the receiving user receives the encrypted text; alternatively, the time-based information may be a combination of time information and time-based threshold information, which may include a specific time indicating that the sending user performed the encryption operation on the input panel of the input method, or a time-based threshold specifying that the receiving user is valid to decrypt the encrypted text within a time-based threshold after the specific time that the sending user performed the encryption operation.

For example, if the sending user inputs the text to be encrypted in the input box of the input method, that is, "my password is 11223344", and the time for clicking the encryption button on the input panel corresponding to the input method is 2016, 11, 3, and 12:00 "in beijing time, the processing device 102 adds the time information of the encryption operation, that is," 2016, 11, 3, and 12:00 "in beijing time, 2016, to the specific field of the encrypted text, when encrypting the information to be encrypted. Further, the processing device 102 may add corresponding time period threshold information of the decryption operation to the specific field of the encrypted text, for example, within 5 minutes, so that the original text information can be decrypted only when the corresponding receiving user performs the decryption operation on the encrypted text within 5 minutes after the time that the sending user performs the encryption operation, that is, before 2016, 11, 3, 12:05 in beijing.

Here, when the device 1 encrypts the text to be encrypted, the aging information of the encryption operation is considered in combination, and only when the aging information is effective, the encrypted text can be decrypted, so that the personal privacy of the user is further protected, and the use experience of the user is improved.

Preferably, the processing device 102 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method and in combination with the identification information of the sending user, so as to obtain the encrypted text.

Specifically, the sending user may further have corresponding identification information, such as identification information of an account information, an IP address, an equipment number, and the like of the sending user, when the sending user performs an encryption operation on an input panel corresponding to an input method by clicking an encryption button, the processing device 102 obtains the identification information of the sending user based on the encryption operation of the sending user, and when performing an encryption process on a text to be encrypted, adds the identification information of the sending user to a specific field of the encrypted text. Therefore, when the corresponding receiving user receives the encrypted characters, the identification information of the sending user can be extracted, so that the identity of the sending user is verified, and whether the encrypted characters can be decrypted or not is judged.

Here, when the device 1 encrypts the text to be encrypted, the identification information of the sending user is considered, and only when the identification information is valid, the identity of the sending user is verified, so that the encrypted text can be decrypted, the personal privacy of the user is further protected, and the use experience of the user is improved.

Preferably, the processing device 102 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method and in combination with the character string with semantic logic stored in the password library, so as to obtain the encrypted text.

Specifically, a character string with semantic logic is stored in the password library, such as "i eat roasted pork rice today", "weather is good today", and the like, when a sending user needs to encrypt a text to be encrypted (original text), "my password is 11223344" which is input in an input box of an input method, for example, as shown in fig. 2, and an encryption operation is performed by clicking an encryption button or the like in an input panel corresponding to the input method; the obtaining device 101 obtains the characters to be encrypted, which are input by the sending user in the input box; the processing device 102 selects a character string with semantic logic for the character to be encrypted from the password library according to the character to be encrypted, for example, "i eat roasted pork rice" today, takes the character string with semantic logic as the character after encryption processing of the character to be encrypted, and establishes a temporary mapping relationship between the character to be encrypted, "i's password is 11223344" and the character string with semantic logic, "i eat roasted pork rice" today; the providing device 103 provides the encrypted text "i eat roasted pork rice today" to the sending user in the input box of the input method, as shown in fig. 3, the sending user may continue to send the encrypted text to the corresponding receiving user by clicking a send button or the like on the input panel of the input method. When the receiving user receives the encrypted text, that is, the character string "i eat roasted pork rice today", it is used as the text to be decrypted and decrypted, and it is input into the input box of the input method by copying and pasting, as shown in fig. 4, the processing device 102 finds the corresponding original text "i have roasted pork rice today" from the password library according to the temporary mapping relationship, and it is used as the decrypted text, and the providing device 103 provides the decrypted text "i have 11223344" to the receiving user in the input box of the input method, as shown in fig. 5; further, after the processing device 102 completes the decryption process, the mapping relationship temporarily established between the text to be encrypted, "my password is 11223344" and the string with semantic logic, "i eat roasted meat rice today", may be released.

Here, the code library stores a character string with semantic logic, and a mapping relationship between the text to be encrypted and the character string with semantic logic may be established as needed, and the code library may be located in the apparatus 1 or in a third-party device connected to the apparatus 1 via a network.

Here, the device 1 performs encryption processing on the text to be encrypted in combination with the password library in which the character string having semantic logic is stored, and since the encrypted text is the character string having semantic logic, even if the chat conversation between the sending user and the receiving user is seen by others, the chat information is not known to be encrypted, thereby further protecting the personal privacy of the user and improving the use experience of the user.

Preferably, the sending user and the receiving user use the same input method, and the apparatus 1 may be located in a server corresponding to the input method, for example, so that the messages of the sending user and the receiving user can be encrypted/decrypted.

Preferably, the user is a receiving user who needs to decrypt the text, wherein the obtaining device 101 obtains the text to be decrypted input by the receiving user in the input box of the input method, wherein the text to be decrypted includes the identification information of the corresponding sending user; the processing device 102 determines whether a sending user corresponding to the identification information and the receiving user are in the same conversation process based on a decryption operation of the receiving user on an input panel corresponding to the input method; if so, carrying out corresponding decryption processing on the characters to be decrypted to obtain the decrypted characters.

Specifically, if the user is a receiving user who needs to decrypt a text, when the receiving user receives an encrypted text sent by a corresponding sending user, the encrypted text is used as a text to be decrypted, and is input into an input box of an input method, for example, by means of copying and pasting, and the like, and the obtaining device 101 obtains the text to be decrypted input into the input box of the input method by the receiving user, for example, by calling an Application Program Interface (API) provided by the user equipment or other agreed communication manners one or more times, where the text to be decrypted includes identification information of the corresponding sending user, such as identification information of an account number, an IP address, a device number, and the like of the sending user; then, the receiving user performs decryption operation by, for example, clicking a decryption button on an input panel corresponding to an input method, the processing device 102 extracts corresponding identification information of the sending user, such as account information, an IP address, an equipment number, and the like of the sending user, from a specific field of the text to be decrypted based on the decryption operation of the receiving user on the input panel corresponding to the input method, and further, the processing device 102 determines whether the sending user corresponding to the identification information is in the same conversation process with the receiving user, that is, determines whether the sending user and the receiving user are communicating; if yes, the processing device 102 performs corresponding decryption processing on the text to be decrypted to obtain decrypted text, and then the providing device 103 provides the decrypted text to the receiving user in the input box of the input method; if not, the processing device 102 does not perform any processing on the text to be decrypted.

Preferably, the user is a receiving user who needs to decrypt characters, wherein the obtaining device 101 obtains the characters to be decrypted input by the receiving user in an input box of the input method, wherein the characters to be decrypted include time-dependent information; the processing device 102 determines whether the aging information is valid based on a decryption operation of the receiving user on an input panel corresponding to the input method; and if so, carrying out corresponding encryption/decryption processing on the characters to be decrypted to obtain the decrypted characters.

Specifically, if the user is a receiving user who needs to decrypt a text, when the receiving user receives an encrypted text sent by a corresponding sending user, the encrypted text is used as a text to be decrypted, and is input into an input box of an input method, for example, by copying and pasting, and the like, and the obtaining device 101 obtains the text to be decrypted, which is input into the input box of the input method by the receiving user, for example, by calling an Application Program Interface (API) provided by the user equipment or other agreed communication methods one or more times, where the text to be decrypted includes aging information. Here, the time-based information may be, for example, only time information indicating a specific time at which the sending user performs an encryption operation by clicking a specific button on an input panel of the input method; or a time period threshold information, which may specify that the encrypted text is valid to be decrypted within a time period threshold, for example, within 5 minutes, when the receiving user receives the encrypted text; alternatively, the time-based information may be a combination of time information and time-based threshold information, which may include a specific time indicating that the sending user performed the encryption operation on the input panel of the input method, or a time-based threshold specifying that the receiving user is valid to decrypt the encrypted text within a time-based threshold after the specific time that the sending user performed the encryption operation.

Then, the receiving user performs decryption operation by, for example, clicking a decryption button on an input panel corresponding to the input method, and the processing device 102 extracts corresponding aging information from the specific field of the character to be decrypted based on the decryption operation of the receiving user on the input panel corresponding to the input method, and determines whether the aging information is valid based on the current time; if yes, the processing device 102 performs corresponding decryption processing on the text to be decrypted to obtain decrypted text, and then the providing device 103 provides the decrypted text to the receiving user in the input box of the input method; if not, the processing device 102 does not perform any processing on the text to be decrypted.

For example, in the process that the receiving user carries out a chat conversation with the corresponding sending user, the receiving user receives the encrypted text "i eat roasted pork rice today" sent by the sending user, wherein the encrypted text comprises aging information, for example, the specific time "11 months, 3 months, 12:00 days in beijing, 2016", that the sending user clicks an encryption button in an input panel corresponding to an input method is included, and of course, the aging information may not be displayed to the receiving user; subsequently, the receiving user inputs the encrypted text "i eat roasted pork rice today" into an input box of an input method by means of copying, pasting, and the like, and takes the encrypted text as a text to be decrypted, and the obtaining device 101 obtains the text to be decrypted, wherein the text to be decrypted includes age information "12: 00 12/3/11/2016/11/beijing time"; then, the receiving user clicks a decryption button in an input panel of the input method of the receiving user, and the processing device 102 extracts corresponding aging information "12: 00/11/3/11/2016 beijing" in beijing time from a specific field of the character "i eat roasted pork rice" to be decrypted based on the decryption button; assuming that the time period threshold preset by the system is 10 minutes, that is, the system is preset within 10 minutes after the specific time of the sending user for performing the encryption operation, and it is only valid that the receiving user decrypts the encrypted text, the processing device 102 determines that the aging information is valid according to the current time, for example, the current time is 2016, 11, 3, 12:08 in beijing; subsequently, the processing device 102 performs corresponding decryption processing on the text to be decrypted to obtain a decrypted text.

For another example, the aging information included in the encrypted text (text to be decrypted) received by the receiving user includes not only the specific time "beijing time 2016, 11, 3, 12: 00" when the sending user clicks the encryption button in the input panel corresponding to the input method, but also the corresponding time period threshold information of the decryption operation, such as 5 minutes, that is, only if the receiving user performs the decryption operation on the encrypted text within 5 minutes after the time when the sending user performs the encryption operation, the original text information can be decrypted; the processing device 102 determines that the aging information is invalid according to the current time, if the current time is 2016, 11, 3, 12:08 in beijing, and the processing device 102 does not perform any processing on the character to be decrypted.

Preferably, the user is a receiving user who needs to decrypt text, wherein the device further comprises a receiving device (not shown). The receiving device receives characters to be decrypted sent by a corresponding sending user, wherein the characters to be decrypted are displayed in a preset format; the obtaining device 101 obtains the text to be decrypted, which is input by the receiving user in the input box of the input method and is displayed in the predetermined format.

Specifically, if the user is a receiving user who needs to decrypt the text, the receiving device receives the encrypted text sent by the corresponding sending user as the text to be decrypted, for example, by calling an Application Program Interface (API) provided by the user equipment or other agreed communication manners one or more times, where the text to be decrypted is presented in a predetermined format, for example, in a predetermined format different from other normal conversations, such as in different fonts and font sizes, or in a form of thickening, tilting, or in a form of shading with a predetermined color, so as to be different from other messages, so as to prompt the receiving user to decrypt the message. Subsequently, the receiving user inputs the to-be-decrypted text displayed in the predetermined format into an input box of the input method by copying and pasting, and the obtaining device 101 obtains the to-be-decrypted text displayed in the predetermined format input by the receiving user in the input box of the input method, for example, by calling an Application Program Interface (API) provided by the user equipment or other appointed communication manners one or more times.

Here, the device 1 presents the encrypted text sent by the sending user to the receiving user in a predetermined format, so as to prompt the receiving user to decrypt and view the message, thereby further improving the use experience of the user.

In step S601, the apparatus 1 acquires a character to be encrypted/decrypted, which is input by the user in the input box of the input method.

Specifically, the user inputs the text to be encrypted/decrypted in the input box of the input method of the user equipment through interaction with the user equipment, and in step S601, the apparatus 1 obtains the text to be encrypted/decrypted, which is input by the user in the input box of the input method, for example, by calling an Application Program Interface (API) or other appointed communication method provided by the user equipment one or more times.

In step S602, the device 1 performs corresponding encryption/decryption processing on the text to be encrypted/decrypted based on the encryption/decryption operation of the user on the input panel corresponding to the input method, so as to obtain the encrypted/decrypted text.

Specifically, after the user inputs the text to be encrypted/decrypted into the input box of the input method, the user performs an encryption/decryption operation on the input panel by, for example, clicking a specific button, and in step S602, the device 1 performs corresponding encryption/decryption processing on the text to be encrypted/decrypted based on the encryption/decryption operation of the user, for example, performs corresponding encryption/decryption processing on the text to be encrypted/decrypted by using technologies such as a symmetric key and an asymmetric key, so as to obtain the encrypted/decrypted text.

Here, the input panel may have, for example, an "encryption button" and a "decryption button" corresponding thereto, and the user clicks the encryption button, and in step S602, the device 1 performs an encryption operation corresponding to the character to be encrypted, and if the user clicks the decryption button, in step S602, the device 1 performs a decryption operation corresponding to the character to be decrypted, and preferably, the encryption button and the decryption button may be, for example, the same button.

In a preferred embodiment, in step S602, the apparatus 1 performs corresponding encryption/decryption operations on the text to be encrypted/decrypted of the user, for example, through a password library. For example, a character string is stored in the password library, when a user needs to encrypt a character to be encrypted (original character), in step S602, the device 1 selects a character string from the password library for the character to be encrypted, uses the character string as a character after encryption processing of the character to be encrypted, and establishes a temporary mapping relationship between the character to be encrypted and the character string, and when a receiving user receives the encrypted character, that is, the character string, uses the character string as a character to be decrypted and performs decryption processing, in step S602, the device 1 finds a corresponding original character from the password library according to the temporary mapping relationship according to the character string, and uses the original character as a decrypted character and provides the decrypted character to the receiving user. Preferably, the character string stored in the password library may be a character string having semantic logic, such as "i eat roasted meat meal today", "weather is good today", etc., so that even if the chat conversation between the sending user and the receiving user is seen by others, the piece of chat information is not known to be encrypted.

In step S603, the apparatus 1 provides the encrypted/decrypted text to the user in the input box of the input method.

Specifically, in step S603, the device 1 provides the encrypted/decrypted characters to the user in the input box of the input method according to the encrypted/decrypted characters obtained in step S602, so that the user can perform subsequent operations, for example, the user can click a send button to send the encrypted characters, or delete the decrypted characters in the input box, thereby inputting other characters that the user wants to input. When the user clicks the encryption/decryption button on the input panel of the input method, the characters to be encrypted/decrypted in the input frame of the input method can be converted into the encrypted/decrypted characters.

Preferably, the user is a sending user who needs ciphertext, wherein the method further comprises step S604 (not shown). In step S604, the device 1 transmits the encrypted text to the corresponding receiving user based on the transmitting operation of the transmitting user on the encrypted text.

Specifically, if the user is a sending user who needs to encrypt a text, the sending user types and inputs a text to be encrypted in an input box of an input method of the user equipment through a physical keyboard, a virtual keyboard and the like through interaction with the user equipment, in step S601, the apparatus 1 obtains the text to be encrypted, which is input in the input box of the input method by the sending user, for example, by calling an Application Program Interface (API) or other appointed communication methods provided by the user equipment one or more times; subsequently, in step S602, the device 1 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method, so as to obtain an encrypted text; in step S603, the apparatus 1 provides the encrypted text to the user in the input box of the input method; next, the transmitting user performs a transmission operation on the encrypted text by, for example, clicking a transmission button, and the device 1 transmits the encrypted text to the corresponding receiving user based on the transmission operation of the transmitting user in step S604.

More preferably, in step S602, the device 1 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method and in combination with the aging information of the encryption operation, so as to obtain an encrypted text.

Specifically, the encryption operation may have certain aging information, and in step S602, when the device 1 encrypts the text to be encrypted, the aging information of the encryption operation may be added to a specific field of the encrypted text. The time information may be, for example, only time information indicating a specific time at which the sending user clicks a specific button on an input panel of the input method to perform an encryption operation; or a time period threshold information, which may specify that the encrypted text is valid to be decrypted within a time period threshold, for example, within 5 minutes, when the receiving user receives the encrypted text; alternatively, the time-based information may be a combination of time information and time-based threshold information, which may include a specific time indicating that the sending user performed the encryption operation on the input panel of the input method, or a time-based threshold specifying that the receiving user is valid to decrypt the encrypted text within a time-based threshold after the specific time that the sending user performed the encryption operation.

For example, if the sending user inputs the text to be encrypted in the input box of the input method, that is, "my password is 11223344", and the time for clicking the encryption button on the input panel corresponding to the input method is 2016, 11, 3, 12:00 "in beijing, then in step S602, when the device 1 encrypts the information to be encrypted, the time information of the encryption operation, that is," 2016, 11, 3, 12:00 "in beijing is added to the specific field of the encrypted text. Further, in step S602, the apparatus 1 may further add corresponding time period threshold information of the decryption operation to the specific field of the encrypted text, for example, within 5 minutes, so that the original text information can be decrypted only if the corresponding receiving user performs the decryption operation on the encrypted text within 5 minutes after the time that the transmitting user performs the encryption operation, that is, before 2016, 11, 3, 12:05 in beijing.

Preferably, in step S602, the device 1 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method and in combination with the identification information of the sending user, so as to obtain encrypted text.

Specifically, the sending user may further have corresponding identification information, such as identification information of an account information, an IP address, an equipment number, and the like of the sending user, and when the sending user performs an encryption operation by clicking an encryption button or the like on an input panel corresponding to an input method, in step S602, the device 1 acquires the identification information of the sending user based on the encryption operation of the sending user, and when performing encryption processing on a character to be encrypted, adds the identification information of the sending user to a specific field of the encrypted character. Therefore, when the corresponding receiving user receives the encrypted characters, the identification information of the sending user can be extracted, so that the identity of the sending user is verified, and whether the encrypted characters can be decrypted or not is judged.

Preferably, in step S602, the device 1 performs corresponding encryption processing on the text to be encrypted based on the encryption operation of the sending user on the input panel corresponding to the input method and in combination with the character string with semantic logic stored in the password library, so as to obtain the encrypted text.
