The invention relates to a method, party challenging device (18) and computer program products for providing a challenge to a first terminal (10) intending to communicate with a second terminal (24) via two networks (N1, N2). The party challenging device receives a first electronic message (1M) concerning a transfer of media from the first terminal to the second terminal sent from the first terminal (10) and addressed to the second terminal (24), obtains communication contextual data associated with the first party or the first terminal, provides an electronic challenge message (CHM) including a challenge (CHl1) based on the obtained data and sends the challenge message to the first terminal in order to enable a decision to be made how to process the invitation message for the second terminal based on the correctness of a response (RM) including a response to the challenge.
A method for providing a challenge to a first terminal intending to communicate with a second terminal via at least one communication network, the method being performed in a party challenging device and comprising the steps of:
The method according to any previous claim, wherein the communication contextual data comprises challenge presentation capability defining data.
The method according to any previous claim, further comprising the step of receiving communication contextual data from the first terminal.
The method according to any previous claim further comprising the step of receiving communication contextual data from at least one communication contextual data providing node in the at least one communications network.
The method according to any previous claim, wherein the communication contextual data comprises session type identifying data.
The method according to any previous claim, comprising the step of receiving said electronic response message, determining the correctness of the response and treating the first electronic message according to policy rules provided for correct responses if the response is correct and otherwise treating the first electronic message according to policy rules provided for incorrect responses.
The method according to any previous claim, wherein the communication contextual data includes challenge preference data provided by the first party.
The method according to any previous claim, wherein the electronic challenge message is a message of the type completely automated public Turing-test to tell computers and humans apart (CAPTCHA).
A party challenging device for providing a challenge to a first terminal intending to communicate with a second terminal via at least one communication network and comprising:
A computer program comprising computer program code which when run on a party challenging device for providing a challenge to a first terminal intending to communicate with a second terminal via at least one communication network, causes said party challenging device to:
