Providing a content preview

A system for providing a content preview, comprising:

• a processor;
• and
• a memory containing instructions that, when executed, cause the processor to:
• split, via a processor, a content item into at least a first fixed size block containing a unique portion of the content item and a second fixed size block containing a unique portion of the content item, in response to a preview triggering event;
• compute a first hash identifier by using at least a part of the unique portion of the first fixed size block as a first hash key in a hashing algorithm;
• compute a second hash identifier by using at least a part of the unique portion of the second fixed size block as a second hash key in the hashing algorithm;
• generate a block list containing a hash key created by concatenating the first hash identifier and the second hash identifier;
• and
• create a content preview of the content item in response to a content preview of the content item not existing based on the generated block list.

A non-transitory computer-readable medium containing instructions for providing a content preview wherein the instructions, when executed by a computing device, cause the computing device to:

• split, via a processor, a content item into at least a first fixed size block containing a unique portion of the content item and a second fixed size block containing a unique portion of the content item, in response to a preview triggering event;
• compute, via the processor, a first hash identifier by using at least a part of the unique portion of the first fixed size block as a first hash key in a hashing algorithm;
• compute, via the processor, a second hash identifier by using at least a part of the unique portion of the second fixed size block as a second hash key in the hashing algorithm;
• generate, via the processor, a block list containing a hash key created by concatenating the first hash identifier and the second hash identifier;
• and
• create, via the processor, a content preview of the content item in response to a content preview of the content item not existing based on the generated block list.
