Method and apparatus of performing data executable integrity verification
View Patent ↗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:
decompressing an application to one or more executables and one or more libraries;
initiating an installation of the application on a computer device;
hashing the one or more executables and the one or more libraries to create one or more hash values;
transmitting the one or more hash values to a hash value server;
storing the one or more hash values in memory at the 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 rehash values with the one or more stored hashed values;
ending the installation of the application on the computer device when the created hash value does not match the pre-stored hash value; and
continuing the installation of the application on the computer device when the created hash value does match the pre-stored hash value.
2. The method of claim 1 , wherein the comparing the one or more hash values to a pre-stored hash value further comprises comparing the one or more hash values to a pre-stored hash value included with the application.
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. An apparatus, comprising:
a processor configured to:
decompress an application to one or more executables and one or more libraries;
initiate an installation of the application; hash the one or more executables and the 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; transmit the one or more hash values to a hash value server; and
a memory, at the 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 rehash values with the one or more stored hashed values;
end the installation of the application when the created hash value does not match the pre-stored hash value; and
continue the installation of the application when the created hash value does match the pre-stored hash value.
7. The apparatus of claim 6 , wherein the processor being configured to compare the hash value to a pre-stored hash value further comprises comparing the hash value to a pre-stored hash value included with the application.
8. The apparatus of claim 6 , wherein the hash value is optionally stored locally.
9. The apparatus of claim 6 , comprising a receiver configured to receive the application.
10. The apparatus of claim 6 , comprising a memory configured to store the one or more executables and the one or more libraries.
11. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform:
decompressing the application to one or more executables and one or more libraries;
initiating an installation of the application on a computer device;
hashing the one or more executables and the one or more libraries to create one or more hash values;
transmitting the one or more hash value to a hash value server;
storing the one or more hash values in memory at the 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 rehash values with the one or more stored hashed values;
ending the installation of the application on the computer device when the created hash value does not match the pre-stored hash value; and
continuing the installation of the application on the computer device when the created hash value does match the pre-stored hash value.
12. The non-transitory computer readable storage medium of claim 11 , wherein the comparing the hash value to a pre-stored hash value further comprises comparing the hash value to a pre-stored hash value included with the application.
13. The non-transitory computer readable storage medium of claim 11 , 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.
14. The non-transitory computer readable storage medium of claim 11 , wherein the processor is further configured to perform receiving an application at the computer device.
15. The non-transitory computer readable storage medium of claim 11 , wherein the processor is further configured to perform storing the one or more executables and the one or more libraries at the computer device.
