Abstract
A system, method and non-transitory computer readable storage medium comprising instructions that when read by a processor perform receiving a telephony connection request, determining a purported sender telephony number from the telephony connection request, determining additional request information from the telephony connection request, accessing an information source using the purported sender telephony number to determine source information regarding the sender, comparing the source information with the additional request information, based on the comparison, and determining whether the purported sender telephony number is incorrect.
Claims20
A method, comprising:
- using a purported sender telephony number to obtain sender confirmation information regarding a purported sender of a received telephony connection request;
- comparing general request information from the telephony connection request with the sender confirmation information;
- based on the comparison, determining whether the sender of the telephony connection request is different than the purported sender of the telephony connection request;
- in the case the sender of the telephony connection request is determined to be the same as the purported sender of the telephony connection request, allowing the telephony connection request;
- and
- in the case the sender of the telephony connection request is determined to be different than the purported sender of the telephony connection request, denying the telephony connection request.
A non-transitory computer readable storage medium comprising instructions that when read by a processor perform:
- using a purported sender telephony number to obtain sender confirmation information regarding a purported sender of a received telephony connection request;
- comparing general request information from the telephony connection request with the sender confirmation information;
- based on the comparison, determining whether the sender of the telephony connection request is different than the purported sender of the telephony connection request;
- in the case the sender of the telephony connection request is determined to be the same as the purported sender of the telephony connection request, allowing the telephony connection request;
- and
- in the case the sender of the telephony connection request is determined to be different than the purported sender of the telephony connection request, denying the telephony connection request.
A system, comprising:
- a processor;
- and
- memory;
- wherein the processor and the memory are communicably coupled to one another;
- wherein the processor:
- uses a purported sender telephony number to obtain sender confirmation information regarding a purported sender of a received telephony connection request;
- compares general request information from the telephony connection request with the sender confirmation information;
- based on the comparison, determines whether the sender of the telephony connection request is different than the purported sender of the telephony connection request;
- in the case the sender of the telephony connection request is determined to be the same as the purported sender of the telephony connection request, allow the telephony connection request;
- and
- in the case the sender of the telephony connection request is determined to be different than the purported sender of the telephony connection request, denies the telephony connection request.
