SYSTEM AND METHOD FOR SERVER-COUPLED APPLICATION RE-ANALYSIS TO OBTAIN CHARACTERIZATION ASSESSMENT
First Claim
1. A method for re-assessing a data object by a server computer comprising:
- a) at the server computer, receiving data about a data object accessible to a mobile communication device, and storing the data in a data store accessible to the server computer;
b) at the server computer, analyzing the data about the data object to produce a characterization assessment, and storing the characterization assessment in the data store accessible to the server computer;
c) at the server computer, based upon a trigger selected from the group consisting of receipt of more data about the data object, receipt of more data about mobile communication devices, and an update to the server computer analyzing capability, re-analyzing the data about the data object;
d) at the server, based upon the re-analyzing, producing an updated characterization assessment; and
,e) at the server, sending a notification based upon the updated characterization assessment.

Abstract
This disclosure is directed to a system and method for preventing malware, spyware and other undesirable applications from affecting mobile communication devices (e.g., smartphones, netbooks, and tablets). A mobile communication device uses a server to assist in identifying and removing undesirable applications. When scanning an application, a device transmits information about the application to a server for analysis. The server receives the information, produces a characterization assessment and can also provide a characterization re-assessment for the application, or data object, and transmits the assessment to the device. By performing analysis on a server, the invention allows a device to reduce the battery and performance cost of protecting against undesirable applications. The servers transmits notifications to devices that have installed applications that are discovered to be undesirable. The server receives data about applications from many devices, using the combined data to minimize false positives and provide comprehensive protection against known and unknown threats. The server can accumulate this data and then perform a characterization re-assessment of a data object it has previously assessed.

19. A non-transitory computer readable storage medium for use with a server computer to re-assess a data object, the non-transitory computer readable storage medium containing computer readable instructions, which when executed by a processor cause the processor to perform the steps of a method comprising:
-
a) at the server computer, receiving data about a data object accessible to a mobile communication device, and storing the data in a data store accessible to the server computer; b) at the server computer, analyzing the data about the data object to produce a characterization assessment, and storing the characterization assessment in the data store accessible to the server computer; c) at the server computer, based upon a trigger selected from the group consisting of receipt of more data about the data object, receipt of more data about mobile communication devices, and an update to the server computer analyzing capability, re-analyzing the data about the data object; d) at the server, based upon the re-analyzing, producing an updated characterization assessment; and
,e) at the server, sending a notification based upon the updated characterization assessment. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
