Fingerprint template protection by adopting random projection based on re-encryption
In random projection (RP) based biometric template protection methods,the generated template and key are vulnerable to attacks,which may cause the leakage of users’ privacy.To solve this problem,an improved RP-based fingerprint template protection method was proposed.First,based on the RP result,the...

| Summary: | In random projection (RP) based biometric template protection methods,the generated template and key are vulnerable to attacks,which may cause the leakage of users’ privacy.To solve this problem,an improved RP-based fingerprint template protection method was proposed.First,based on the RP result,the proposed method divided the projection domain into fingerprint matching domain and noise adding domain that were mutually independent,then fused them with two sub-matrices of the random projection matrix and saved the result as template.In addition,re-encryption mechanism was introduced to realize secure storage and transmission of the key (RP matrix).Experimental results show that the proposed method can achieve stronger ability to resist different attacks than existing RP-based biometric template protection methods,and also guarantee high matching accuracy and revocation. |
