Name collision is a situation where names chosen by Secure Hash Algorithms ([[SHA]]) to represent a specific data object maybe shared by two different data objects. This name collision problem could allow one to submit a '''fake''' document or '''fake''' data object that has the same digital digest (the name), therefore confound the authenticity of information.

SHA stands for Secure Hash Algorithm. It is a way to encode data with an asymmetric data encoding function. There are many implementations of this class of algorithms, generally known as SHA-0,SHA-1,SHA-2,SHA-3.
A Shattered SHA-1 Function
It is public knowledge that Google had cracked SHA-1 and presented a website called:shattered.io to disclose their findings. You can even test if your document encoded using SHA-1 has name collisions or not. Name collision is a situation where names chosen by Secure Hash Algorithms (SHA) to represent a specific data object maybe shared by two different data objects. This name collision problem could allow one to submit a fake document or fake data object that has the same digital digest (the name), therefore confound the authenticity of information. An example of name collision can be found on shattered.io.
