Method for evaluating a document

1. A method for verifying a user's identity, comprising:

connecting a first and a second data processing device for data communication;

running a software application in the second data processing device;

for user verification, receiving user identification data in the second data processing device, the user identification data comprising reference data;

receiving one or more images of a document assigned to the user in the second data processing device;

determining measurement data from image data providing a digital representation of the one or more images;

comparing the reference data to the measurement data determined from the digital representation of the one or more images;

providing verification data in the second data processing device, the verification data indicative of the user's identity being verified in the step of comparing the reference data to the measurement data;

transmitting the image data from the second data processing device to the first data processing device;

generating, by a processor, an operation identification number assigned to the image data transmitted from the second data processing device to the first data processing device, wherein the operation identification number is transmitted from the processor to the second data processing device and the operation identification number is transmitted from the second data processing device to the first data processing device, the operation identification number being a unique identifier of an identification operation for the user, and including a randomly generated: number, characters, or a sequence of numbers and/or characters.

2. The method of claim 1 , further comprising transmitting the verification data from the second data processing device to the first data processing device.

3. The method of claim 1 , further comprising generating a tamper-proofed operation identification number.

4. The method of claim 1 , further comprising storing the image data together with the operation identification number in a storage device assigned to the first data processing device.

5. The method of claim 1 , further comprising capturing the one or more images by a camera of the second data processing device.

6. The method of claim 1 , further comprising providing both the user identification data and the one or more images showing a user's face in the second data processing device.

7. The method of claim 1 , further comprising: storing the image data in a storage device assigned to the first data processing device.
