Further, the technical features involved in the different embodiments of the present application described below may be combined with each other as long as they do not constitute a conflict with each other.

Example 1

This embodiment provides a method for deleting user terminal information, as shown in FIG. 1A, including the following steps:

S10: Receive a deletion code sent by another user terminal, where the deletion code is used to request to delete the information.

For example, when the user terminal B is lost, the user terminal A can be used to send a deletion code to the user terminal B, requesting to delete the information in the user terminal B. The user terminal can be a mobile terminal, such as a smart phone, or a non-mobile terminal that communicates with each other, such as two desktop computers connected to the Internet. For example, the user terminal B is a mobile terminal, and the user terminal A is a non-mobile terminal.

S20: Determine whether the deletion code is consistent with the preset information deletion password. If they are consistent, step S30 is performed. If they are inconsistent, no operation is performed.

The preset information deletion password includes a combination of one or more of letters, numbers, and underscores, and includes a combined number of transmissions, and may further include a time interval between two consecutive transmission times being less than a predetermined time interval. For example, the preset information deletion password is three consecutive times "good_moring_9981", and the interval between the next transmission and the last transmission is less than 5 minutes.

S30: Delete the stored information.

In the above example, if the preset information deletion password of the user terminal B is three consecutive times "good_moring_9981", the user terminal A can only delete the information in the user terminal B by continuously transmitting "good_moring_9981" three times to the user terminal B. Otherwise, if the user terminal A only transmits twice, or the content of the transmission is "good_moring9981" or "good_moring_998", the information in the user terminal B cannot be deleted.

Preferably, the preset information deletion password includes a first preset information deletion password for deleting only the stored picture information, and/or a second preset information deletion password for deleting only the stored text information, and/or Or a third preset information for deleting all stored information to delete the password. This allows different content to be deleted as needed, reducing unnecessary deletion of information.

The user terminal information deletion method provided by the embodiment of the present invention determines whether the deletion code is consistent with the preset information deletion password by receiving the deletion code sent by another user terminal. If the deletion code is consistent, the stored information is deleted, so that the user can conveniently and quickly The information in the remote user terminal is deleted, and the information stored in the lost user terminal is protected from being leaked.

As a preferred embodiment of the present embodiment, as shown in FIG. 1B, the preset information deletion password is stored in the user terminal and sent to the designated information receiving account, and the designated information receiving account includes the designated electronic mailbox. For example, after setting the preset information deletion password in the user terminal B, the password is saved in its own memory for comparing the deletion code sent by another user terminal; and is also sent to the user-specified email address to help the user remember the pre-order. The information deletion password is set, especially in the case that the user terminal B is lost, a way is provided for acquiring the preset information deletion password in the lost user terminal.

If the user forgets the default password deletion password in the user terminal B that has been lost, and accidentally deletes the email with the preset information deletion password, the user can obtain the preset information deletion password by the following steps:

S40: Receive a search code sent by another user terminal, where the search code is used to request to find a preset information to delete the password.

S50: Determine whether the search code is consistent with the preset search password. If they are consistent, perform step S60. If they are inconsistent, do not perform any operation.

S60: Send the preset information deletion password to the specified information receiving account.

The preset search password can be set as a simple password. If the user terminal A continuously sends three "3"s to the lost user terminal B, and the interval between two adjacent transmissions is within 5 seconds, the user terminal B can The preset information deletion password of the user terminal B is sent to the designated email address, so that the user can view the email to obtain the preset information deletion password, and send the information to the user terminal B according to the deletion to delete the user terminal B. information.

Since the search code is consistent with the preset search password, the preset information deletion password is sent to the designated information receiving account, so it is not easy to leak, and the security is high, so the preset search password can be set as a simple password to facilitate the memory. .
