Method for secure transmission using a fax server, system and computer program for implementing this method
View Patent ↗A method for secure transmission using a fax server, including transmitting a document to be faxed, by a sender to a server, in the form of a digital file in a non-fax format, as well as information relative to the identity of the recipient; calculating a Tiff format file from the digital file on the one hand, the creation time and date of the file and an informative file on the other hand; calculating a signature from said Tiff document and entering the result of this calculation in an additional file; recording the files in a secured space accessible by the sender and the recipient; modifying the Tiff file to be transmitted to insert the signature and information allowing the recipient to access the recorded files; transmitting the file by the server to the telephone address of the recipient, according to a fax standard, and issuing a transmission report by the server in the form of an electronic message in a non-fax format.
1. A method for secure transmission using a fax server, comprising:
receiving a document to be faxed, by a server from a sender, in the form of a digital file in a non-fax format, as well as information relative to the identity of a recipient of the document;
calculating a Tiff format file from said digital file on the one hand, the creation time and date of said digital file and an informative file on the other hand;
calculating a signature from said Tiff format file and entering the result of the calculation in an additional file;
recording said Tiff format and additional files in a secured space accessible by the sender and the recipient;
modifying said Tiff format file to be transmitted to insert said signature and information allowing the recipient to access said recorded Tiff format and additional files;
transmitting said Tiff format file by the server to a telephone address of the recipient, according to a fax standard, and
issuing a transmission report by the server in the form of an electronic message in a non-fax format,
wherein the method further comprises modifying said Tiff format file into a different format file and transmitting said different format file to the sender for verification and validation before said recording.
2. The method for secure transmission using a fax server according to claim 1 , wherein said information allowing the recipient to access said Tiff format and additional files is recorded in the form of image files corresponding to a plurality of languages, the selection of the linguistic file being determined by the sender.
3. The method for secure transmission using a fax server according to claim 1 , wherein the different format file is a pdf file.
4. The method for secure transmission using a fax server according to claim 1 , wherein said Tiff format file is time-stamped before being converted to the different format file.
5. The method for secure transmission using a fax server according to claim 1 , wherein said modifying includes inserting said signature and information at a last page of the Tiff format file.
6. The method for secure transmission using a fax server according to claim 1 , wherein said TiFF format file is verified and validated by the sender before said recording.
7. The method for secure transmission using a fax server according to claim 1 , wherein said document and said signature are archived for several years.
8. The method for secure transmission using a fax server according to claim 1 , notifying the sender when the recipient accesses said recorded Tiff format file for the first time.
9. A secure transmission system using a fax server, comprising a server interacting with a conversion and signature server carrying out conversion of a file received by the conversion and signature server, the system being configured to:
receive a document to be faxed, by the server from a sender, in the form of a digital file with a non-fax format, as well as information relative to the identity of a recipient of the document;
calculate a Tiff format file from said digital file on the one hand, the creation date and time of said digital file and an informative file on the other hand;
calculate a signature from said Tiff format file and entering the result of the calculation in an additional file;
record said Tiff format and additional files in a secured space accessible by the sender and the recipient;
modify said Tiff format file to be transmitted to insert said signature and information allowing the recipient to access said recorded Tiff format and additional files;
transmit said Tiff format file by the server to a telephone address of the recipient, according to a fax standard, and
issue by the server a transmission report in the form of an electronic message in a non-fax format,
wherein the system is further configured to modify said Tiff format file into a different format file and to transmit said different format file to the sender for verification and validation before recording said Tiff format and additional files in the secured space.
10. A non-transitory computer readable medium encoded with instructions for carrying out a method for secure transmission using a fax server, the method comprising:
receiving a document to be faxed, by a server from a sender, in the form of a digital file in a non-fax format, as well as information relative to the identity of a recipient of the document;
calculating a Tiff format file from said digital file on the one hand, the creation time and date of said digital file and an informative file on the other hand;
calculating a signature from said Tiff format file and entering the result of the calculation in an additional file;
recording said Tiff format and additional files in a secured space accessible by the sender and the recipient;
modifying said Tiff format file to be transmitted to insert said signature and information allowing the recipient to access said recorded Tiff format and additional files;
transmitting said Tiff format file by the server to a telephone address of the recipient, according to a fax standard, and
issuing a transmission report by the server in the form of an electronic message in a non-fax format,
wherein the method further comprises modifying said Tiff format file into a different format file and transmitting said different format file to the sender for verification and validation before said recording.
