Embodiment Construction

[0029] figure 1 It is a flowchart of Embodiment 1 of a method for storing data information of a terminal device provided by the present invention, such as figure 1 As shown, the method includes:

[0030] Step 101: The cloud server receives data information to be stored sent by the first terminal device;

[0031] Step 102: The cloud server encrypts the data information using the first encryption key, stores the encrypted data information, and sends the first decryption key corresponding to the first encryption key to the first encryption key. Terminal Equipment;

[0032] Step 103: The cloud server dynamically generates a second encryption key, and uses the second encryption key to re-encrypt the data information, stores the re-encrypted data information, and encrypts the second encryption key. The second decryption key corresponding to the key is sent to the first terminal device.

[0033] The terminal device involved in this embodiment may be a mobile terminal, such as a smart phone,...

Abstract

The invention provides a data information storage method for terminal equipment, the terminal equipment and a cloud terminal server. The method comprises the steps that the cloud terminal server receives data information to be stored of the first terminal equipment; the cloud terminal server adopts a first encryption key to conduct encryption on data information, stores the encrypted data information, and sends a first decryption key corresponding to the first encryption key to the first terminal equipment; the cloud terminal server generates a second encryption key, adopts a second encryption key to conduct encryption on the data information again, stores the data information which is encrypted again, and sends a second decryption key corresponding to the second encryption key to the first terminal equipment; therefore, dynamic encrypted storage of the data information is achieved, and the safety of data information cloud terminal storage is effectively improved.

Description

Technical field [0001] The invention relates to a data storage technology, in particular to a method for storing data information of a terminal device, a terminal device and a cloud server. Background technique [0002] People generally store some important data information in terminal devices (such as mobile phones, laptops, etc.). However, once the terminal device is lost or connected by other devices, it is easy to cause the loss of user data information. [0003] At present, with the continuous development of cloud services, storing data information in terminal devices in the cloud can free up the storage space of communication terminal devices and avoid the risk of data information loss due to the loss of communication terminal terminal devices. A relatively simple way to realize cloud storage of data information is to upload the data information to the cloud, and the cloud performs fixed and conventional encrypted storage of the data information. [0004] However, the above-m...
