Embodiment Construction

[0030] In the present invention, the barcode image can be a one-dimensional code, a two-dimensional code or a multi-dimensional code; although the amount of stored information of the one-dimensional code is limited, it is also feasible in theory; to elaborate.

[0031] Below in conjunction with accompanying drawing, the present invention will be further described; figure 1 , based on time, location, random number and barcode photo punching or evidence collection method, it is characterized in that, its steps are as follows:

[0032] 1) Record the network time 2 at the shooting moment of camera 1 to avoid falsification of the shooting time recorded by the image by modifying the local system time; the network time is granted by a credible third party, and cannot be modified because the time taken by the user comes from the Internet; When not connected to the network, record the status information of the network not connected to distinguish;

[0033] 2) Record the camera positi...

Abstract

The invention discloses a shooting method based on network time, positioning, direction, random number, barcode and digital encryption technology, which prevents the falsification of shooting time and shooting content, and is suitable for taking pictures, checking in attendance, law enforcement and evidence collection, etc. field of fraud. In addition, the present invention also provides a method for effectively retrieving whether an image has been edited and a method for storing header information of a paper image based on a two-dimensional code.

Description

technical field [0001] The invention obtains the real information of the shooting behavior and content by recording the network time, location, and compass direction parameters of the camera shooting moment, combined with random numbers, barcodes, and digital encryption technology when taking pictures or taking pictures, which can be applied to attendance check-in, Fields such as law enforcement and evidence collection that require that the shooting behavior and content cannot be falsified. Background technique [0002] Traditionally, it is easy to falsify when shooting with a camera, and it is not easy to judge whether the content of the shooting is falsified. The falsification of shooting usually takes the following forms: [0003] One is to falsify the shooting time; the first way of falsification is: when taking pictures with a normal camera, the time of taking pictures is taken from the local system time of the camera, and the photographer can falsify by setting the loc...
