## Abstract

A method for collectively delivering electronically certified credentials is disclosed. In one aspect, the method includes a) collecting personal data related to credential recipients and including a valid electronic mail address, b) collecting data related to each credential to be delivered to each recipient at a granting authority, c) sending to a centralized server of a certifying authority the collected data of each recipient, the data being stored in a centralized database, d) sending an personalized e-mail corresponding to each recipient, the e-mail including a link to the centralized server, for approval of the data related to the each recipient, and e) activation of the electronic credential.

## Background
FIELD OF THE INVENTION
The disclosed technology is related to a centralized method and a system for certifying electronic (dematerialized) credential.
DESCRIPTION OF THE RELATED TECHNOLOGY
Nowadays, the exchange of information is performed predominantly by dematerialised media, such as internet website, e-mail, SMS, . . . . This is particularly true in job prospection, more particularly when the potential employer is geographically distant from the job applicant (recipient).
In that case, the potential employer usually has difficulties to verify the accuracy of the data given in a personal resume. In some critical cases, it could be needed to verify the diploma of the recipient by, for example, calling the academic institution which has granted the diploma. This represents high costs for the potential employer and is time consuming for both the academic institution and the potential employer.
It is known in the art to use centralized databases for credentials associated to individuals such as described in US patent application 2012/0116907 to simplify the access to certified credential information by interested third parties (such as potential employer). That document discloses, a method wherein an individual asks a service provider to certify the authenticity of all information in a resume, each information being verified by inquiry to granting authority before being certified. The verified resume information is then kept on a database for later access to interested third parties. From the granting authority point of view, this means that such request can be performed at any time, which again represents a time consuming activity.

DETAILED DESCRIPTION OF CERTAIN ILLUSTRATIVE EMBODIMENTS
Certain embodiments relate to a centralized method and a centralized system for collectively delivering certified credential from a granting authority.
By “centralized”, it is meant that more than one credential can be delivered at once from a granting authority, and that all credentials related to all recipients can be delivered and stored on the same delivering system.
Advantageously, the credentials delivered are related to diploma, or credentials used in professional resumes which are collectively granted at particular dates (for example, for all successful students at the end of the academic year, or participants to professional continuous training workshop, . . . ).
In one embodiment, the granting authority collects first the list of recipients to be granted, along with the data related to the corresponding credential.
In one embodiment, there are two types of data, dynamic data related to each recipients, and static data related to the credential itself (template credential).
The granting authority then sends the collected data to the server. Preferably, the upload of the collected data is performed by means of a secured communication channel wherein the verification of the identity of the authority is performed before the upload process.
The data received by the server is then stored in a database located in the server, and an e-mail is sent to the recipient of the credential, for verification and activation. The sent e-mail comprises an hyperlink to a web page (preferably a dynamic web page) comprising the data related to the corresponding credential.
In one embodiment, the data related to each recipient may be encrypted before being stored on the database, the unique key necessary to decrypt the data being comprised in the e-mail sent to the corresponding recipient, and the e-mail sent to each recipient is deleted from the server after sending, so that the encrypted data cannot be retrieved (and decrypted) without the explicit consent of the recipient.
Once the recipient has received the e-mail comprising the unique key, he can follow the hyperlink to the corresponding web page on the server and provide the unique key for authorising the decryption of the corresponding credential data. A credential in electronic format is then generated, using the decrypted data. A copy of the generated credential is then stored on the server database, and an hyperlink to the credential is given to the recipient for subsequent use.
Advantageously, more than one document can be generated upon activation, for example, in case of multiple credentials related to one academic program.
It should be noticed at this stage that even if the activation e-mail is intercepted by a malicious third party, it can only be used to generate the credential related to the right recipient (i.e. the third party cannot obtain an undue credential by using the decrypting key).
The recipient can then print the generated credential, or save it in electronic format for further use. Advantageously, the printed credential comprises a graphically coded URL pointing to the server for an easy verification of its authenticity by an interested third party such as a potential employer. For example, the printed credential can comprise a QR-code coding the URL pointing to the credential of the certifying server.
The recipient can then share the certified credential with interested third parties either by directly sending printed or electronic credentials, or by including in a communication an URL pointing to the certified credential on the centralized server. This last procedure is particularly useful for sharing certified credential related to professional resume on professional social network.
The electronic credential can also include an electronic signature for off-line verification of the authenticity of the credential.
FIG. 1 presents one embodiment of the invention. In that embodiment, an authority 1 sends 3 to a centralized server 4 data 2 related to credentials to be granted to recipients 6.
Upon reception of data 2 related to the credentials to be granted, the centralized server 4 encrypts the data to maintain privacy of the data received in server 4 without the explicit consent of the recipients 6 and sends a communication 5 to each recipient 6. The data related to the communication is deleted from the server 4 after the sending process, so that, only encrypted data is kept in the server.
Therefore server 4 comprises at least means for receiving data such as for example a POP server for receiving e-mails from the authority 1. Preferably, it further comprises means for authenticating the source of the communication 3. This can be done for example by means of a dynamic web page requesting a login and a password, the granting authority being able to upload the data to the server only if a valid login and password have been provided.
The encryption of the data can be done by means of known encryption algorithm using a unique encryption key for each recipient, for example coded by php on a dynamic web server such as apache. The encrypted data can then be stored for example on a SQL database such as a MySQL server. The unique encryption key can for example be generated by a random number generator.
Alternatively, the unique key can be derived from the identification key of the granting authority, so that the authority can decrypt the individual data of the recipient for further follow-up (status verification, re-sending of the activation e-mail to another e-mail address, . . . ).
The communication 5 sent to each recipient comprises the unique activation and decryption key and an hyperlink to a dynamic web page on server 4, the data related to each recipient and the corresponding credential being decrypted only if and when the recipients gives explicit consent to the storage of data on the server 4. For example, the hyperlink points to a dynamic webpage located on the server, the hyperlink comprising the data permitting to php code to retrieve the encrypted data related to the receiving recipient. The then generated dynamic webpage comprises a key field wherein the recipients fills his unique decryption key thereby giving explicit consent for the storage of his data. The decryption key can advantageously be included in the hyperlink, so that the recipient does not need to write it in a form.
After reception of the explicit consent of the recipients, the server decrypts the corresponding data and make the corresponding electronic credential available for downloading by the recipient. Advantageously, the generated credential comprises an electronic certificate which can be verified offline. The recipient can then send 8 the generated electronic credential to interested third party 9.
In one embodiment, the electronic credential further comprises a hyperlink to the database 4 for further verification of the authenticity of the credential online. Such hyperlink can have the form of a classic hyperlink on an electronic document, but, can also be coded as a visual code recognisable by a computer or a smartphone, such as a QR-code. In that case, even printed credential can easily be verified online.
The hyperlink comprised on each credential are interpreted by the webserver on the server 4 to generate the corresponding credential based upon the decrypted data located on the server. Again, this can be done on webserver comprising php interpreter and coupled to an SQL database.
