This paper proposed a birthmark method that uses fuzzy
hashing to enable faster comparison and is designed for use
with existing birthmark methods. The proposed method defines
two preprocessing steps, sort and memoization. We evaluated
the proposed method on three existing birthmark types. The results
show that the proposed method can improve comparison
speed and preserve the property of distinction that birthmarks
possess. However, we found it greatly reduces preservation, so
its use would require a lower similarity threshold or similar
adjustment.
The following areas need to be covered in future studies:
refining the proposed method to improve preservation, evaluating
its preservation in response to other obfuscation methods,
and evaluating its use with other birthmark extraction methods.
