Abstract

The invention discloses a method, a device and equipment for protecting data. The method is applied to second equipment, and specifically comprises the following steps that: in the case that first equipment is connected with the second equipment, the second equipment obtains a first identification and a second identification, wherein the first identification is the unique identification of the first equipment, and the second identification is the unique identification of the second equipment; and whether the first identification is matched with the second identification is judged, if the first identification is not matched with the second identification, then specified data in the first equipment and / or the second equipment are set to be in a protected state. Special hardware peripherals have no need to be added during an application for the method, the device and the equipment for protecting data disclosed by the invention, and the specified data in the first equipment and the second equipment are protected via hardware authentication according to the identifications (ID) of the equipment; and therefore, the method, the device and the equipment for protecting data are low in cost and high in safety.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and equipment for protecting data. Background technique [0002] At present, electronic devices, such as mobile phones, computers, and tablet computers (PADs), have been widely used. When two devices are connected, how to ensure the security of data in each device is a problem that must be considered. The current workaround is: [0003] 1. Protect the data in the two devices through a pure software method. [0004] This method has poor security performance and is easy to be cracked. [0005] 2. Protect the data in the two devices through hardware. [0006] The current hardware encryption technology needs to add special hardware peripherals; therefore, the cost is high. Contents of the invention [0007] Embodiments of the present invention provide a data protection method, device, and equipment, which realize data protection at low cost and high s...
