An identification control method and system for a valuable document. The system comprises a collection part, an identification part, a control part, a transmission part and an upper computer. In the identification part, complete identification information about a valuable document is split into basic identification information and high-grade identification information. Only the basic identification information which is required by the control part is sent to the control part, and the information which is not required by the control part is directly sent to the upper computer by the identification part. The identification part only transmits the basic identification information to the control part, the data transmission amount is one-tenth of the original data transmission amount, and the transmission speed can be increased by 10 times, thereby solving the problem that a valuable document cannot be quickly processed continuously because the serial transmission speed between the control part and the identification part is slow.

Identification control method and system for valuable document

Disclosed are a valuable-file identifying method and an identifying device thereof. The identifying method and the identifying device store image data of a valuable file using a fast storage method for image data. The fast storage method for image data comprises: compulsively converting collected single-byte image data into long-integer image data; using N data masks which correspond to each other through a 'bitwise AND' operation to extract the long-integer image data in such a manner that N points are extracted from M*N points in each line and one point is extracted from L points in each column, where N is an integer greater than or equal to 2, L and M are all integers greater than or equal to 1; and integrating the data extracted respectively by N data masks through a 'bitwise OR' operation to obtain coded image data and store same. In conclusion, the present invention converts single-byte image data into long-integer image data, and extracts multipoint data at one time using a plurality of data masks which correspond to each other, reducing the number of operations, and achieving fast, compressed storage of images.

Fast storage method for image data, valuable-file identifying method and identifying device thereof

An identification method for a valuable file and an identification device thereof. The method includes the following steps: (1) acquiring an original infrared image, type, denomination and orientation data of a current valuable file; (2) obtaining size data and infrared characteristic data of a corresponding standard valuable file; (3) applying an image projection conversion technology, and correcting the original infrared image to form a second infrared image matched with the size of the standard valuable file; (4) obtaining the infrared characteristic data of the current valuable file from the second infrared image and comparing same with that of the standard valuable file to identify whether the current valuable file is true or false; and (5) outputting the identification result. This method and device correct the original infrared image, reducing the quality acquisition requirements thereof, and can collect an image directly using a camera on a simply equipped mobile device, improving identification accuracy.
