Data theft is a growing phenomenon in order to gain useful information for the attackers own benefits over the victims sensitive data. The loss caused by this fraudulent act is severe as what happened to the Equifax data breach in 2017. Here cryptography and steganography are applied to secure identity data contained in the electronic Indonesian identity card (e-KTP). Cryptography has been used for decades to secure data in storage. Steganography is often added after the cryptography process to provide two layers of protection. The elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. The ECC is used here to secure the Indonesia identity card data. Least significant bit steganography is used after the ECC to embed the information (cipher text) into the person picture. Thus the only stored information in the application is a collection of photos. The testing and evaluation show that the implementation is successful with the PSNR value above 79 dB.
