Abstract

A system allows the display of a private file on a screen of a telecommunications terminal. This system includes a first and a second Internet site. In the first Internet site, a first image contains a coded link to an address of a file of the second Internet site. The private file is stored in encrypted form in the meta data of the file in the second Internet site. A program recognizes the coded link and searches the meta data of the file whose Internet address corresponds to the coded link for authorization of a person connected to the first Internet site to view the private file. The program downloads the private file of the second Internet site via a remote protocol from the telecommunications terminal if viewing is authorized, to display the private file on the screen.

Claims

1. A system allowing the display of a private computer file on a screen of a telecommunications terminal, said system including:

a first and a second Internet site;

in the first Internet site, a first image comprises a coded link to an address of a file of the second Internet site, wherein said private computer file is stored in encrypted form in the meta data of the file in said second Internet site; and

a program able to recognize said coded link and to search through the meta data of the file whose Internet address corresponds to said coded link to locate authorization of a person connected to the first Internet site, to view the private computer file, and wherein said program downloads said private computer file of the second Internet site, via a remote protocol from said telecommunications terminal if said viewing is authorized, to display the private computer file on said screen.

2. A system according to claim 1, wherein said coded link is a QR code.

3. A system according to claim 1, wherein said private computer file is an image.

4. A system according to claim 1, wherein said telecommunications terminal is a computer.

5. A system according to claim 1, wherein said telecommunications terminal is a mobile phone.

6. A system according to claim 1, wherein said remote protocol is selected from among one of the following protocols:

http,

https, or

ftp.

7. A system according to claim 1, wherein said program is an extension of a web browser.

8. A system according to claim 1, wherein said first image includes, in addition to said coded link, the image of a padlock.

9. A system according to claim 1, wherein said file is an image including, in the data portion thereof, the image of a padlock.

10. A system according to claim 1, wherein said program verifies:

whether a digital identifier of said person exists in the meta data of said file, with said digital identifier being selected from among;

said person'"'"'s e-mail address,

said person'"'"'s name on a social network platform,

and wherein, if said digital identifier exists, said program decrypts said private computer file on-the-fly in order to display it on said screen, said program using for the decrypting operation a secret in possession of the person whose digital identity is contained in the meta data of said file of said second Internet site.

11. A computer system configured to implement an Internet site, called the first Internet site, and storing a first image comprising a coded link to the address of a file of a second Internet site at which a private computer file is stored.

12. The computer system according to claim 11, wherein the first Internet site is composed of a social network.

13. A computer system implementing an Internet site, called the second Internet site, said Internet site storing a file comprising meta data containing an encrypted private computer file as well as a directory of encrypted forms of a key which has been used for encrypting said private computer file, said key having been encrypted by public keys of persons entitled to view said private computer file in a decrypted form, wherein each one of said encrypted forms of keys is associated with a digital identifier of a person having been granted a right of access to said encrypted private computer file.

14. A method for displaying a private computer file on a screen of a telecommunications terminal, said terminal being connected to a first Internet site, comprising:

displaying, in said first Internet site, a first image comprising a coded link to an address of a file of the second Internet site, wherein said private computer file is stored in encrypted form in meta data of the file in said second Internet site;

recognizing, by means of a program said coded link and searching through the meta data of the file whose Internet address corresponds to said coded link for authorization of a person connected to the first Internet site to view said private computer file, and

downloading said private computer file via a remote protocol from said telecommunications terminal, if said viewing is authorized, to display the private computer file on said screen.

15. A computer readable storage medium having stored thereon a program allowing the display of a private computer file on a screen of a telecommunications terminal, said program including instructions that cause a computer to execute the following operatons:

encrypting said private computer file, by means of a key, in order to obtain an encrypted private computer file;

storing said encrypted private computer file in meta data of a file in an Internet site, called the second Internet site;

generating at least one encrypted form of said key by means of a public key of a person entitled to view said private computer file;

storing said encrypted form of said key in the meta data of said file of said second Internet site;

generating a coded link of the address of said file of said second Internet site;

include said coded link in an image, called the first image stored in another Internet site, called the first Internet site;

upon displaying of said first image on said screen, recognizing said coded link and searching through the meta data of said file whose Internet address corresponds to said coded link for authorization of a person connected to the first Internet site to view said private computer file,

downloading via a remote protocol from said telecommunications terminal said private computer file of said second Internet site, if said viewing is authorized, to display the private computer file on said screen.
