Computer systems for generating certified data

A computer system for generating certified data, the computer system comprising:

• an electronic device equipped with an apparatus for acquiring visual and/or sound data, a locator and a memory, said device being configured to establish a Global System for Mobile communications (GSM) network connection;
• a computer program residing in said memory, said program being configured to start the apparatus, acquire visual and/or sound data and, during the data acquisition step, start the locator and acquire a location of the device;
• a system database;
• and
• a first server and a second server, managed by a first certification body and a second certification body respectively;
• wherein said program is configured to:
• start the GSM network connection and access a website that provides a certified time, and acquire such time at the same time as the step of acquiring the visual and/or sound data,
• storing said data, said location and said time in a reserved portion of said memory, such that it can be only accessed by the program,
• associating information elements comprising an alphanumeric identification axle, said position and said time, with said stored visual and/or sound data,
• sending said stored visual and/or sound data and said information elements associated with the visual and/or sound data to said system database and said first server,
• said first server is configured to generate a certified e-mail message containing said stored visual and/or sound data and said information elements associated with the stored visual and/or sound data and to send it to said second server,
• said second server is configured to archive the content of said certified email message to generate evidence containing archiving information, and send the evidence to the system database, and
• upon reception of the evidence, said system database is configured to generate a document containing the information elements associated with the stored visual and/or sound data, and to send said data and said document to a user-specified e-mail address.
