Method and apparatus of performing data executable integrity verification
Disclosed are an apparatus and method of verifying an application installation procedure. One example method of operation may include receiving an application at a computer device and initiating the installation of the application on the computer device. The method may also provide executing the application during the installation procedure and creating a hash value corresponding to the executed application data. The method may further provide storing the hash value in memory and comparing the hash value to a pre-stored hash value to determine whether to continue the installation of the application.
1. A method, comprising:
hashing, at a computer device, one or more executables and one or more libraries to create one or more hash values;
storing the one or more hash values in memory at a hash value server;
transmitting a query to the memory at the hash value server to verify the one or more hash values of the one or more executables;
rehashing the one or more executables and one or more libraries each time the one or more executables are executed to create one or more rehash values;
comparing the one or more hash values to a pre-stored hash value included with the application;
ending an installation of an application on the computer device if the created hash value does not match the hash value stored in the memory; and
continuing the installation of the application on the computer device if the created hash value does match the hash value stored in the memory;
wherein an installation of the application is initiated on the computer device.
2. The method of claim 1 , comprising comparing the one or more rehash values with the one or more stored hashed values.
3. The method of claim 1 , wherein storing the one or more hash values in memory optionally comprises storing the one or more hash values locally on the computer device.
4. The method of claim 1 comprising receiving the application at the computer device.
5. The method of claim 1 , comprising storing the one or more executables and the one or more libraries at the computer device.
6. The method of claim 1 , comprising transmitting the one or more hash values to the hash value server.
7. An apparatus, comprising:
a processor configured to:
hash, at a computer device, one or more executables and one or more libraries to create one or more hash values of the one or more executables and one or more libraries of the application; and
a memory, at a hash value server, configured to store the one or more hash values; and
wherein the processor is further configured to:
transmit a query to the memory at the hash value server to verify the one or more hash values of the one or more executables;
rehash the one or more executables and one or more libraries each time the one or more executables are executed to create one or more rehash values;
compare the one or more hash values to a pre-stored hash value included with the application;
end an installation of an application if the created hash value does not match the hash value stored in the memory; and
continue the installation of the application if the created hash value does match the hash value stored in the memory;
wherein an installation of the application is initiated on the computer device.
8. The apparatus of claim 7 , wherein the processor is configured to compare the one or more rehash values with the one or more stored hashed values.
9. The apparatus of claim 7 , wherein the hash value is optionally stored locally.
10. The apparatus of claim 7 , comprising a receiver configured to receive the application.
11. The apparatus of claim 7 , comprising a memory configured to store the one or more executables and the one or more libraries.
12. The apparatus of claim 7 , wherein the processor is configured to transmit the one or more hash values to a hash value server.
13. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:
hashing, at a computer device, to create one or more hash values;
storing the one or more hash values in memory at a hash value server;
transmitting a query to the memory at the hash value server to verify the one or more hash values of the one or more executables;
rehashing the one or more executables and one or more libraries each time the one or more executables are executed to create one or more rehash values;
comparing the one or more hash values to a pre-stored hash value included with the application;
ending an installation of an application on the computer device if the created hash value does not match the hash value stored in the memory; and
continuing the installation of the application on the computer device if the created hash value does match the hash value stored in the memory;
wherein an installation of the application is initiated on the computer device.
14. The non-transitory computer readable storage medium of claim 13 , comprising comparing the one or more rehash values with the one or more stored hashed values.
15. The non-transitory computer readable storage medium of claim 13 , wherein the storing the one or more hash values in memory optionally comprises storing the one or more hash values locally on the computer device.
16. The non-transitory computer readable storage medium of claim 13 , wherein the processor is further configured to perform receiving an application at the computer device.
17. The non-transitory computer readable storage medium of claim 13 , wherein the processor is further configured to perform storing the one or more executables and the one or more libraries at the computer device.
