Abstract: The computer implemented method comprising: receiving a first server a request in the name of a user to be logged into a service of said first server and authenticating said request by verifying user identification information of said user, wherein a second server in connection with a user computing device with a dedicated program is used for: receiving a request about a status associated to said user; initializing a credential exchange in order to provide mutual authentication; verifying said associated status that has been previously set as valid or as invalid by said user; and sending said associated status to said first server wherein the latter allows the logging of said request or rejects it if said associated status is set as valid or as invalid.

Abstract: The computer implemented method comprising controlling the access to different resources and actions defined for a user by a first server, reducing the exposure time at which such operations are available, establishing a dual channel verification through the use of a second server and reinforcing an authentication factor mechanism by including a biometric identity verification of biometric information of the user.

Abstract: A computer implemented method and computer program products to prevent attacks against authorization systems The computer implemented method comprising controlling the access to different resources and actions defined for a user by a first server, reducing the exposure time at which such operations are available and establishing a dual channel verification through the use of a second server. The computer programs implement the method.

Abstract: A computer implemented method and computer program products to improve security in authentication/authorization systems The computer implemented method comprising controlling the access to different resources and actions defined for a user by a first server, reducing the exposure time at which such operations are available, establishing a dual channel verification through the use of a second server and a defining a secure channel for certificate exchange for authentication. The computer programs implement the method.
