A method of establishing communication between mobile terminals includes receiving a communication request from a caller terminal, the communication request including at least a caller number and information for determining an identification code of a callee terminal, the information including a number of the callee terminal or an owner name of the callee terminal. The method also includes obtaining the identification code of the callee terminal based on the information and inquiring about a corresponding record associated with the caller terminal and the callee terminal by use of a pre-stored address book referencing relationship and a communication history, based on the caller number and the identification code of the callee terminal. The method further includes computing a communication right value based on the corresponding record and determining whether the computed communication right value exceeds a pre-determined threshold. In response to a determination that the computed communication right value exceeds the pre-determined threshold, communication between the caller terminal and the callee terminal is established.

An automated method for determining the validity of an incoming phone call including receiving an incoming phone call, activating a controller in response to receipt of the incoming phone call, wherein the controller generates a multi-digit code in response to the receipt of the incoming call, outputs an audible version of the multi-digit code to a caller for the incoming call, requests the caller to input the multi-digit code, compares the multi-digit code with a caller input, determines the call is invalid in response to a mismatch between the multi-digit code and the caller input, and terminates the phone call.

Concepts and technologies for handling and screening incoming calls are provided. A processor executing instructions associated with a call handling service can detect that a call from a calling party is being routed, via a communication interface, to a called party device associated with a customer. The processor can obtain caller identification data that can specify an identity that is generated by the calling party and intended to be representative of the calling party when presented to the customer by the called party device. The processor can determine an interface identifier associated with the communication interface, and retrieve a call authentication scenario based on the interface identifier. The call authentication scenario can specify a storage location of data. The processor can obtain the data from the storage location, determine a call handling action, prepare a call handling command, and provide the call handling command to a network.

A telephone call processor for processing telephone calls comprising voice signals and data signals, the call processor comprising a first telephone interface and a second telephone interface, the call processor being operable in a first mode and in a second mode. In the first mode, the call processor is adapted to receive voice signals and data signals at the first telephone interface and to transmit voice signals and data signals via the second telephone interface. In the second mode, the call processor is adapted to receive voice signals and data signals at the first telephone interface, to block data signals from being transmitted via the second telephone interface and optionally to transmit voice signals via the second telephone interface.

A method for blocking unwanted calls has been provided. The includes intercepting a call being routed from a calling device to a receiving device. The intercepting occurs prior to the call being presented to the receiving device for an answer. The method further determines further routing of the intercepted call by comparing parameters of the intercepted call to one or more lists. If it is determined that the call should be authenticated, the method sends an authentication challenge to the calling device. If a response is received to the authentication challenge, the method determines whether the response is correct. If the response is correct, the method routes the call to the receiving device.

A method and apparatus for easily restricting a use right and improving use convenience in a mobile terminal are provided. The method includes displaying a profile list for selecting a set operation mode of the mobile terminal from the displayed profile list; setting an operation mode of the mobile terminal as the selected operation mode, when the set operation mode is selected from the displayed profile list; and displaying a screen associated with the selected operation mode, wherein the set operation mode includes an open mode to use all functions of the mobile terminal and a limited mode to use only set functions.

A backup account recovery authentication of last resort using social authentication is described. The account holder requests trustees who have been previously identified to obtain an account recovery code. The account recovery system sends a communication to the trustee for information to verify the trustee as one of the previously identified trustees. The account recovery system then may transmit a link and code with instructions for the trustee to return the link. The account recovery system then transmits a situational query to the trustee to provide additional security. Finally, if all the communications have been completed for the required level of security, the account recovery code is transmitted to the trustee. The trustee sends the account recovery code to the account holder for access to an account.
