Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

An embodiment of the present invention provides an encryption method for encrypting data, as shown in Figure 1, the encryption method includes the following steps:

Step 101: Determine the character password sequence used to encrypt the target data.

Specifically, multiple character sequences are preset in the system, and the preset character sequences are also default character sequences. The characters included in the preset character sequence may be numbers, letters or symbols, and the preset character sequence may be any combination of numbers, letters and symbols. For example, the preset character sequence may be: "123456789", "jklmopqr", "2046, ap_" and so on. Based on the user's selection operation on the preset character sequence, the character password sequence can be determined from multiple sets of preset character sequences, for example, according to the user's selection operation, "123456789" is determined as the character password sequence.

In addition, the user can also input the character password sequence by himself, and determine the character password sequence based on the user's input operation, for example, according to the user's input operation, determine "2016az, sSy5k" as the character password sequence. Similarly, the characters contained in the character password sequence input by the user may be numbers, characters or symbols, and the character password sequence may be any combination of numbers, characters and symbols. When the character password sequence is obtained based on the user's input operation, after the character password sequence is determined, the character password sequence can be stored locally and/or in the cloud for subsequent use.

Step 102: Associating the character password sequence with the sliding track corresponding to the sliding operation performed by the user on the graphical input interface to generate a character graphic password.

Specifically, the graphical input interface includes at least one key grid, and the user can arbitrarily set the position of the key grid in the graphical input interface according to actual needs. For example, the graphical input interface can include 9 key grids, and the 9 key grids can Jiugongge forms are distributed in the graphical input interface. Further, accepting the user's sliding operation in the graphical input interface can obtain a sliding track corresponding to the sliding operation.

Regarding how to associate the character password sequence with the sliding track, in the first embodiment, firstly, the characters in the character password sequence are filled into each key cell included in the graphical input interface, and each character corresponds to a key cell. Wherein, when the number of characters contained in the character password sequence is less than the number of key grids contained in the graphical input interface, after filling according to the preset filling rules, some of the key grids are filled with characters, and the other part of the key grids are still blank key grids. When the number of characters included in the character password sequence is equal to the number of key cells included in the graphical input interface, all the key cells in the graphical input interface are filled with characters after being filled according to a preset filling rule. When the number of characters contained in the character password sequence is greater than the number of key cells contained in the graphical input interface, only the same number of characters as the number of key cells contained in the graphical input interface is filled in each key cell. Among them, the preset filling rule can be arbitrarily set according to the actual needs of the user. For example, when the key grids in the graphical input interface are distributed as nine-square grids, the preset filling rule can be from left to right and from top to bottom. Characters are filled into each key cell. Next, accept the user's sliding operation in the graphical input interface, and sequentially extract the characters in each key grid passed by the sliding track while obtaining the sliding track corresponding to the sliding operation, and extract the corresponding key grids and the corresponding key grids passed by the sliding track. Each character is associated to generate a character graphic password.

For example, when the determined character password sequence is "123456789", fill "123456789" into the Jiugongge key grid in the graphical input interface, as shown in Figure 2, and then accept the sliding operation of the user in the graphical input interface, Obtain the sliding trajectory corresponding to the sliding operation, that is, the sliding trajectory with a shape of "3", and extract the characters in each key cell that the sliding trajectory passes through while obtaining the sliding trajectory with a shape of "3", which are "12487" in sequence, Each character in the extracted "12487" is associated with each key grid in the sliding track with the shape of "3", thereby generating the first character graphic password. As another example, when the determined character password sequence is "jklmnopqr", fill "jklmnopqr" into the Jiugongge key grid in the graphical input interface, and then accept the user's sliding operation in the graphical input interface to obtain the The sliding trajectory of the sliding trajectory, that is, the sliding trajectory with the shape of "7", while obtaining the sliding trajectory with the shape of "7", extract the characters in each key cell that the sliding trajectory passes through, which are "jklnq" in turn, and the extracted Each character in "jklnq" is associated with each key grid in the sliding track with the shape of "7", so as to generate the second character graphic password. In this application, multiple character and graphic passwords can be combined, and the target data can be encrypted using the combined character and graphic password, for example, after the first character and graphic password is generated, the first character and graphic password is cached, and then Adopt the same method to generate the second character graphic password, as shown in Figure 3, at last, utilize the first character graphic password and the second character graphic password to encrypt the target data, thereby, when the encrypted target data is decrypted, It is necessary to ensure that the first character graphic password is successfully verified and then the second character graphic password is successfully verified, so that the target data can be decrypted.

For associating the character password sequence with the sliding track, in the second embodiment, first, accept the user's sliding operation in the graphical input interface, and sequentially add the character password sequence to the corresponding sliding track while obtaining the sliding track corresponding to the sliding operation. The characters of are filled into each key grid passed by the sliding track, and each character corresponds to a key grid. Among them, when the number of characters contained in the character password sequence is less than the number of key grids passed by the sliding track, after filling according to the preset filling rules, some of the key grids passed by the sliding track are filled with characters, and the other part of the key grids are filled with characters. Blank grid. When the number of characters contained in the character password sequence is equal to the number of key cells passed by the sliding track, all the key cells in the key cells passed by the sliding track are filled with characters after being filled according to the preset filling rule. When the number of characters contained in the character password sequence is more than the number of key grids passed by the sliding track, the same number of characters as the number of key grids passed by the sliding track will be filled into each key grid, and at the same time, no filling will be performed in the character password sequence characters are cached. Wherein, the preset filling rule can be arbitrarily set according to the actual needs of the user, for example, starting from the first key cell passed by the sliding track, filling characters into each key cell passed by the sliding track sequentially. Next, associate each key cell that the sliding track passes with the characters correspondingly filled in each key cell to generate a character graphic password.

For example, when the determined character password sequence is "2016az," and the sliding track corresponding to the user's sliding operation is a sliding track with a shape of "3", then while obtaining the sliding track with a shape of "3", follow the For the second time, fill "2016az," into each key cell passed by the sliding track, as shown in Figure 4, and associate each key cell passed by the sliding track with the shape of "3" with the corresponding character in "2016az," , to generate a character graphic password. When the determined character password sequence is "2016az, .sSy5k;", if the first sliding track corresponding to the user's first sliding operation is a sliding track with a shape of "3", then after obtaining the first sliding track with a shape of "3", At the same time as a sliding track, "2016az," is filled into each key grid that the first sliding track passes through, and each key grid that the first sliding track with a shape of "3" passes is matched with the corresponding characters in "2016az," Association, generate the first character graphic password, and cache "sSy5k" at the same time, after refreshing the graphic input interface, all the key cells in the graphic input interface are in a blank state, if the user receives the second sliding in the graphic input interface Operation, when obtaining the second sliding track corresponding to the second sliding operation, if the second sliding track is a sliding track with a shape of "Z", while obtaining the second sliding track with a shape of "Z", set ".sSy5k ;" is filled into each key grid passed by the second sliding track, as shown in Figure 5, and each key grid passed by the second sliding track with a shape of "Z" is associated with the corresponding characters in ". , to generate the second character graphic password. Finally, the target data is encrypted using the first character pattern password and the second character pattern password, so that when decrypting the encrypted target data, it is necessary to ensure that the first character pattern password is successfully verified first and then the second character pattern is successfully verified. password to be able to decrypt the target data.

When using the above-mentioned second embodiment to encrypt the target data, generally speaking, the sliding track will only pass through some key grids in the graphical input interface. If the graphical input interface also contains blank key grids after the sliding operation , then, fill in the blank key grid with completion characters, and the completion characters are randomly generated by the system, as shown in Figure 6, and then associate each key grid that the sliding track passes with the corresponding characters filled in each key grid At the same time, the blank key grid is associated with the completion characters filled in the blank key grid to generate a character graphic password. Completing the characters to complete the blank key grid can increase the complexity of generating the character-graphic password, thereby improving the security of the character-graphic password.

In this application, the generated character-graphic password includes a character password and a graphic password, and the character password is associated with the graphic password. Each key grid in the graphic password contains character password information, and the character password is formed from the character password information in all the key grids contained in the graphic password. In addition, each key grid carries position identification information. When the key grid is associated with a character, the character also carries the position identification information of the corresponding key grid, and the previous association between the key grid and the character is realized by using the position identification information.
