System and methods thereof for real-time fraud detection of a telephone call transaction

A method for detecting of fraudulent calls, comprising:

• receiving, by a target node, a call by the target node from an origin node initiating the call;
• generating, by the target node, a first call data record (CDR) that includes at least one call parameter recorded by the target node upon termination of the call;
• receiving, by the target node, a first secure CDR that contains the first CDR, wherein the first secure CDR is received from a node different from the target node;
• and
• generating, by the target node, a fraud notification when the first secure CDR is determined to be invalid.

A Telco provider origin node for detecting of fraudulent calls, comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the origin node to:
• initiate a call to a target node;
• generate a first call data record (CDR) for the call, wherein the CDR includes at least one call parameter of the call recorded by the origin node upon termination of the call;
• generate a first secure CDR that contains the first CDR;
• send the first secure CDR to the target node;
• and
• generate a fraud notification based on a second secure CDR received from a first node and the first secure CDR, wherein the first node is different from the origin node, and wherein the fraud notification is generated in response to a comparison of secure CDRs generated by two different nodes.

A Telco provider target node for detecting of fraudulent calls, comprising:

• a processing circuitry;
• and
• a memory, the memory containing instructions that, when executed by the processing circuitry, configure the target node to:
• receive a call by the target node from an origin node initiating the call;
• generate a first call data record (CDR) that includes at least one call parameter recorded by the target node upon termination of the call;
• receive a first secure CDR that contains the first CDR, wherein the first secure CDR is received from a node different than the target node;
• and
• generate a fraud notification when the first secure CDR is determined to be invalid.
