Abstract

A method of interrupting an incoming call on a mobile device includes: intercepting an incoming telephone call received by a mobile device; determining one or more parameters of the intercepted telephone call; determining if the intercepted telephone call matches one or more telephone calls associated with a list of prohibited phone numbers by comparing the determined parameters of the intercepted call with parameters of the one or more telephone calls associated with the list of prohibited phone numbers; and in response to determining a match between the intercepted telephone call and the one or more telephone calls associated with the list of prohibited phone numbers: blocking reception of the intercepted telephone call; identifying a calling party associated with the intercepted telephone call; sending an authentication request to the identified calling party; and interrupting the intercepted telephone call in response to unsuccessful authentication.

First claim

The invention claimed is:

1 . A method of interrupting an incoming call on a mobile device comprising:
adding a plurality of phone numbers associated with a calling party to a list of prohibited phone numbers; intercepting an incoming telephone call received by a mobile device; determining one or more parameters of the intercepted telephone call; determining if the intercepted telephone call matches one or more telephone calls associated with the list of prohibited phone numbers by comparing the determined parameters of the intercepted call with parameters of the one or more telephone calls associated with the list of prohibited phone numbers; blocking reception of the intercepted telephone call by the mobile device in response to determining a match between the intercepted telephone call and the one or more telephone calls associated with the list of prohibited phone numbers; sending an authentication request to a remote authentication service that contains information about intended telephone calls provided by the calling party before the call for authentication of the intercepted telephone call; and interrupting the intercepted telephone call in response to unsuccessful authentication when the intercepted telephone call is not an intended telephone call; or unblocking the intercepted telephone call in response to successful authentication when the intercepted telephone call is an intended telephone call.

2 . The method of claim 1 , wherein the one or more parameters of the intercepted call are determined based on data transmitted by a mobile operator to a called party for making a connection between the calling party and the called party.

3 . The method of claim 1 , wherein the one or more parameters of the intercepted call comprise one or more of: a telephone number of the calling party, a name of the calling party, a location of the calling party, time of interception of the incoming telephone call.

4 . The method of claim 1 , wherein the authentication request to the remote authentication server includes at least the following information: called party; calling party; one or more parameters of the intercepted call.

5 . The method of claim 1 , wherein the authentication is successful if the remote authentication service acknowledges that the information received in the authentication request matches information provided by the calling party.

6 . The method of claim 1 further comprising: receiving from a calling party a plurality of phone numbers associated with the calling party to be added to the list of prohibited numbers.

7 . A system for detecting an anomaly in the behavior of a trusted process comprising:
a memory and a hardware processor configured to:
add a plurality of phone numbers associated with a calling party to a list of prohibited phone numbers;
intercept an incoming telephone call received by a mobile device;
determine one or more parameters of the intercepted telephone call;
determine if the intercepted telephone call matches one or more telephone calls associated with the list of prohibited phone numbers by comparing the determined parameters of the intercepted call with parameters of the one or more telephone calls associated with the list of prohibited phone numbers; and
block reception of the intercepted telephone call by the mobile device in response to determining a match between the intercepted telephone call and the one or more telephone calls associated with the list of prohibited phone numbers;
send an authentication request to a remote authentication service that contains information about intended telephone calls provided by the calling party before the call for authentication of the intercepted telephone call; and interrupt the intercepted telephone call in response to unsuccessful authentication when the intercepted telephone call is not an intended telephone call; or unblock the intercepted telephone call in response to successful authentication when the intercepted telephone call is an intended telephone call.

8 . The system of claim 7 , wherein the one or more parameters of the intercepted call are determined based on data transmitted by a mobile operator to a called party for making a connection between the calling party and the called party.

9 . The system of claim 7 , wherein the one or more parameters of the intercepted call comprise one or more of: a telephone number of the calling party, a name of the calling party, a location of the calling party, time of interception of the incoming telephone call.

10 . The system of claim 7 , wherein the authentication request to the remote authentication server includes at least the following information: called party; calling party;
one or more parameters of the intercepted call.

11 . The system of claim 7 , wherein the authentication is successful if the remote authentication service acknowledges that the information received in the authentication request matches information provided by the calling party.

12 . The system of claim 7 , wherein the hardware processor further configured to receive from a calling party a plurality of phone numbers associated with the calling party to be added to the list of prohibited numbers.

13 . A non-transitory computer readable medium storing thereon computer executable instructions for detecting an anomaly in the behavior of a trusted process, including instructions for:
adding a plurality of phone numbers associated with a calling party to a list of prohibited phone numbers; intercepting an incoming telephone call received by a mobile device; determining one or more parameters of the intercepted telephone call; determining if the intercepted telephone call matches one or more telephone calls associated with the list of prohibited phone numbers by comparing the determined parameters of the intercepted call with parameters of the one or more telephone calls associated with the list of prohibited phone numbers; blocking reception of the intercepted telephone call by the mobile device in response to determining a match between the intercepted telephone call and the one or more telephone calls associated with the list of prohibited phone numbers; sending an authentication request to a remote authentication service that contains information about intended telephone calls provided by the calling party before the call for authentication of the intercepted telephone call; and interrupting the intercepted telephone call in response to unsuccessful authentication when the intercepted telephone call is not an intended telephone call; or unblocking the intercepted telephone call in response to successful authentication when the intercepted telephone call is an intended telephone call.

14 . The medium of claim 13 , wherein the one or more parameters of the intercepted call are determined based on data transmitted by a mobile operator to a called party for making a connection between the calling party and the called party.

15 . The medium of claim 13 , wherein the one or more parameters of the intercepted call comprise one or more of: a telephone number of the calling party, a name of the calling party, a location of the calling party, time of interception of the incoming telephone call.

16 . The medium of claim 13 , wherein the authentication request to the remote authentication server includes at least the following information: called party; calling party; one or more parameters of the intercepted call.

17 . The medium of claim 13 , wherein the authentication is successful if the remote authentication service
