Fig. 1 is a schematic diagram illustrating an application scenario of a transfer transaction at an ATM according to an embodiment of the present application.
The user may transact a transfer transaction at the ATM 11 and optionally the ATM 11 or the server 12 may create a corresponding electronic voucher. The user may choose to print or not print the electronic voucher. If the ATM creates the electronic voucher, the electronic voucher may be transmitted to the server 12 for storage.
The file format of the electronic certificate created by the ATM machine or the server 12 may be any one of a PDF file format, a word file format, a Txt file format, and an execl file format.
It can be understood that the second information included in the electronic certificate corresponding to different services may be different, and the second information included in the electronic certificate corresponding to different services may be arranged in different manners.
In the embodiment of the present application, information included in the electronic certificate opened in the second file format is referred to as second information, where the second file format is a file format to which the electronic certificate belongs. For example, if the file format of the electronic certificate is a PDF file format, then the second file format of the electronic certificate is a PDF file format; if the file format of the electronic certificate is a Word file format, the second file format of the electronic certificate is a Word file format.
Assuming that the electronic certificate is the electronic certificate 21 in fig. 2, the second information and the layout manner of the second information included in the electronic certificate 21 are only examples, and the embodiment of the present application does not limit the layout manner of the second information and the second information included in the electronic certificate.

In the process of storing the electronic certificate, the server 12 opens the electronic certificate in the first file format, and then obtains attribute information with a preset identifier from first information contained in the electronic certificate opened in the first file format. The attribute information is used for representing whether second information contained in the target electronic certificate opened in the second file format is modified or not.
The second file format of the electronic certificate is different from the first file format; in an optional embodiment, the electronic certificate opened in the first file format includes first information that is at least partially different from second information included in the electronic certificate opened in the second file format, for example, at least the second information does not include attribute information having the preset identifier.
Obtaining a characteristic value corresponding to the electronic certificate at least based on the attribute information; and storing the characteristic value of the electronic certificate and at least part of the second information. Since the attribute information is used for representing whether the second information contained in the target electronic certificate opened in the second file format is modified, the characteristic value corresponding to the electronic certificate can also represent whether the second information is modified based on the attribute information, and therefore whether the second information is modified can be judged based on the characteristic value corresponding to the electronic certificate.

Assuming that the file format of the target electronic certificate is a PDF file format, assuming that the second content contained in the target electronic certificate is as shown in fig. 2 after the target electronic certificate is opened in the second file format, assuming that the first file format is a Txt file format, the target electronic certificate is opened in the Txt file format to obtain a part of the first information as shown in fig. 4. Assuming that the attribute information is a modification time of the second information included in the target electronic certificate, the preset identifier may be ModDate. Then, the attribute information derived from the first information shown in FIG. 4 is "(D: 20190517172204+08 '00')".

Since the attribute information is used for representing whether the second information contained in the target electronic certificate opened in the second file format is modified, the characteristic value corresponding to the obtained electronic certificate can also represent whether the second information is modified based on the attribute information, so that whether the second information is modified can be judged based on the characteristic value corresponding to the electronic certificate.
