The present invention discloses an information processing method and an electronic device, the method being applicable to an electronic device capable of executing a first application, and the method including: detecting at an instance of time T1 whether there is a first predetermined operation, wherein the first predetermined operation is configured to control the electronic device to present a second interface for displaying a set of second applications satisfying a predetermined condition; determining whether the set of second applications includes the first application; and when it is determined that the set of second applications includes the first application, displaying the first application via a third interface in the second interface, wherein the difference between the third interface and a first interface is greater than or equal to a first threshold.

The invention discloses an unlocking device and a method thereof. The unlocking device comprises a sensing unit for sensing actions of a user on an electronic device, a storage unit for storing a music file, a playing module for playing the music file, a setting unit for setting at least one time point of the music files as at least one unlocking time period, a time unit for recording time taken from starting playing the music file to the time point, and a calculation unit; the unlocking device is characterized in that the playing module automatically plays the music file when the electronic device enters an unlocking interface, and then the user conducts an action on the electronic device, the calculation unit determines whether the time point of the action of the user on the electronic device is located within the unlocking time period and an allowed error range thereof, and if so, the unlocking of the screen is accomplished. Due to the adopted unlocking device, when the screen of the electronic device is switched to the unlocking interface, the electronic devices plays music, and the user can achieve the purpose of screen unlocking by conducting an action on the electronic device when the music is played by a predetermined time point, and therefore, the security of cellphone information can be effectively improved, and meanwhile, the entertainment of cellphone unlocking can be enhanced.

The invention discloses a connecting box, which comprises a box bottom and a box cover, wherein the box bottom is connected with the box cover by a connecting rod to implement the fast opening and closing of the connecting box; a single connecting box can be used separately or a plurality of connecting boxes can be combined with one another for use; a plurality of knock-off holes are formed on the side wall of the connecting box; during use, the knock-off holes are knocked off as required, and the sides of two adjacent connecting boxes are connected by patches and wedges; and the connecting box is also convenient to dismount. A sealing ring is arranged between two connecting boxes to play waterproof and dustproof roles during connection; and the connecting rod is provided with a lead seal device for packaging the whole connecting box, so that the connecting box has high safety.

Provided is a file encryption method based on chaos transformation. The file encryption method comprises: (a1) preprocessing a password for encrypted content; (a2) extracting a group of plaintext data and generating the initial values of a group of vertificaiton codes; (a3) obtaining a second iteration coefficient and the number of second iteration times; (a4) executing secret key iteration and generating an iteration result according to the second iteration coefficient and the number of second iteration times; (a5) performing xor operation on the iteration result and the plaintext data; (a6) generating a verification code according to the plaintext data; (a7) writing the result of the xor operation in a file and generating a cryptograph; (a8) determining whether the secret key iteration is executed to the tail portion of the encrypted content, and executing a step (a9) if yes or continuously executing the step (a4) if not; (a9) the successive iteration result of the plaintext data and all the iteration results are converted into integers and the encryption key generated by the last next iteration is saved in the tail of the encrypted content.
