How to confirm that you are the developer of the program?

Question

Payment systems

Now I'm talking with the support service of one of the payment acceptance systems.
Require confirmation of authorship of the program.
I quote: "In order to confirm that you are a developer, you must have previously registered this program in the program catalog and indicate the name of the developer."
What kind of directories are these?
The first time I've heard. I only know about the register of Rospatent.

Answer 1

Copyrights to the programs belong to the physical. to a person on the basis of paragraph 3 of Article 1228 of the Civil Code of the Russian Federation and due to the absence of the fact of the transfer of exclusive property rights to third parties. Registration of programs and obtaining documentary evidence is not mandatory, but a recommended action to protect rights.
In accordance with the provisions of Article 1262 of the Civil Code of the Russian Federation, software is classified as copyright, which does not require mandatory registration with the federal executive authority for intellectual property.
Indirect confirmation of your copyright may be the inclusion of your software in the register of the Russian software of the Ministry of Communications.
