In the embodiment of the present invention, the sending determination module 1043 refuses to send the identity information watermark image when the authorization operation time exceeds the authorization deadline time, authorizes to send the identity information watermark image when the authorization operation time does not exceed the authorization deadline time, and can ensure that the identity information watermark image can only be used for business transaction corresponding to the key purpose information because of the key purpose information of the watermark on the identity information watermark image.

In summary, the embodiment of the present invention obtains the identity information image and records the obtaining time; obtaining authorization deadline and authorization use information to generate key use information; generating an identity information watermark image by the acquisition time and the key purpose information; and accessing the authorized operation time, comparing the authorized operation time with the authorized deadline, and authorizing to send the identity information watermark image when the authorized operation time does not exceed the authorized deadline. The method and the device can watermark the acquired time and the key purpose information to the identity information image, compare the authorization operation time with the authorization deadline time, and perform authorization sending only when the authorization operation time does not exceed the authorization deadline time, so that the identity information can only be authorized and uploaded for special services in a certain time, thereby effectively avoiding identity information leakage, preventing the identity information from being used for other services and damaging the interests of owners.

It should be understood that, although the steps in the flowcharts of the embodiments of the present invention are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in various embodiments may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a non-volatile computer-readable storage medium, and can include the processes of the embodiments of the methods described above when the program is executed. Any reference to memory, storage, database, or other medium used in the embodiments provided herein may include non-volatile and/or volatile memory, among others.
