The invention discloses a file protection method and device. The method comprises the steps of receiving a file search instruction, monitoring a character string in the file search instruction, comparing the character string with a preset code, and returning file interface data corresponding to the preset code if the character string is the preset code. By the adoption of the file protection method and device, privacy and security of private files can be improved.

The application provides a user authentication method. The method comprises following steps: receiving touch behavior data of users collected by a terminal; determining whether touch behavior data of users are matched with habit touch behaviors of authenticated users for the terminal; determining that users are authenticated if does; and determining that users are not authenticated if not. The user authentication method has following beneficial effects: based on touch behavior data of users collected by the terminal, identity authentication is performed; counterfeiting act is avoided; higher safety is obtained; identity authentication is performed when users are not informed of so that the method is secretive; and leakage of personal information is avoided when the terminal is lost.

The invention discloses a fingerprint and face coupling recognition method based on a multiple linear regression associative memory model, comprising the following steps: S1: collecting fingerprint pictures and face pictures; S2: obtaining the associative memory input of the fingerprint pictures and face pictures respectively Matrix and output matrix; S3: Construct multiple linear regression fingerprint image recognition model and multiple linear regression face image recognition model with regression parameters; S4: Calculate regression parameters to obtain multiple linear regression fingerprint image recognition model, multiple linear regression face image Recognition model; S5: Recognize fingerprint pictures and face pictures. Beneficial effects: multiple identification of identity information, high reliability, combination of associative memory and multiple linear regression model, converting pictures into parameters, high safety factor, good recognition effect, good protection effect on identity information, and high privacy.

The invention relates to a movable sealed family nursing cabin for medical caring. The movable sealed family nursing cabin for medical caring comprises rolling wheels and containing frames; supports are embedded at the upper ends of the rolling wheels, rotating shafts are installed at the upper ends of the supports, a cabin body is arranged at the upper portions of the supports, a hydraulic pump is fixed in the middle of the upper end of the cabin body, a crawling ladder is installed at the left end of the front face of the cabin body, a case is fixed at the upper end of the cabin body, the containing frame is installed on the inner wall of the left side of the cabin body, and a protruding rail is fixed at the lower end of the cabin body. According to the movable sealed family nursing cabin for medical caring, through the supports, the movable sealed family nursing cabin ascends and descends on the cabin body through hydraulic rods, and the whole cabin body can be controlled to ascendand descend; when multiple nursing cabins are put in a ward, the nursing cabins can rise, every two nursing cabins can be superposed, and therefore the occupied space of the nursing cabin in the wardcan be reduced; meanwhile, the multiple nursing cabins can be put in the ward, and when the nursing cabins are superposed, the rolling wheels are folded at the lower end of the cabin body through thesupports along the rotating shafts, it is avoided that transient walkers bump on the rolling wheels, and the flexibility of the nursing cabin is improved.

The invention discloses a processing method for the clearance area of ​​a shell, which comprises: providing a shell, the material of which is a conductive material; oxidizing the shell so that an oxide layer is formed on the shell; Protective layer; remove the protective layer and oxide layer in the preset area on the inner surface of the shell; remove the conductive layer in the preset area; remove the remaining protective layer of the shell; make a brightening layer in the clearance area of ​​the shell. The processing method of the clearance area of ​​the housing provided by the embodiment of the present invention removes the conductive layer in the preset area to form a clearance area capable of passing the radio frequency signal of the antenna, and makes a brightening layer on the clearance area, so that the clearance of the housing The color and brightness of the region and the conductive region of the housing are the same, that is, the headroom region has a strong concealment, thereby improving the overall appearance of the housing. The invention also provides a casing and a mobile terminal.

The invention relates to a wheelchair anti-theft device. The wheelchair anti-theft device comprises a beam frame rod on a wheelchair, a signboard, fixing bolts, a functional block, first switches and second switches, wherein the first switches and the second switches are arranged on the functional block and matched with the fixing bolts. The beam frame rod is a hollow pipe with two sealed ends, and the fixing block is fixed in the beam frame rod; the first switches and the second switches are either normally-open reset switches or normally-closed reset switches; a tracer connected with a battery in series is also arranged in the functional block, and the first switches and the second switches are connected at the two ends of the tracer in parallel; the fixing bolts are screwed on the beam frame rod to be capable of pressing the first switches and the second switches to control opening and closing of the first switches and the second switches. As a tracing device is arranged in the beam frame rod of the wheelchair in a sealed mode, and starting of the tracer is related to the fixing bolts for fixing the signboard, the secrecy is achieved; as the switches of a circuit are set as normally-closed and normally-open reset switches which are connected in parallel, the reliability of the circuit can be enhanced, and the operating stability of the tracer is guaranteed.
