Keamanan data sangat penting dilakukan dalam menjaga kerahasiaan informasi itu sendiri, terutama bila informasi tersebut hanya boleh diketahui pihak yang tertentu saja. Pengiriman data atau informasi tanpa dilakukan pengamanan akan beresiko terhadap penyadapan. Sehingga informasi yang ada di dalamnya dapat mudah diketahui oleh pihak-pihak yang tidak berhak, dan hal seperti itu sangat merugikan.Hingga saat ini, kriptografi merupakan salah satu solusi untuk menjamin keamanan dari suatu informasi. Zero Knowledge Proof (ZKP) merupakan protokol kriptografi yang dapat digunakan seseorang untuk membuktikan kepemilikan seseorang (prover) akan suatu informasi rahasia kepada orang lain (verifier), tanpa perlu mengungkapkan informasi tersebut atau memberikan cara bagi orang lain untuk mengetahui rahasia tersebut. Hasil pengujian adalah Zero Knowledge Proof membagi satu aliran data menjadi blok-blok kecil Masing-masing blok ini dienkripsi secara terpisah. Dalam implementasi tanpa bukti pengetahuan, kunci untuk mengenkripsi hanya akan berada pada pengguna, dan dengan itu, ia akan dapat mengenkripsi dan mendekripsi informas, Algoritma zero knowledge proof adalah metode yang unik dimana pengguna dapat membuktikan kepada pengguna lain bahwa dia tahu informasi tambahan.

 LoA or Letter of Acceptance is a statement received. LoA is usually used as a statement of scholarship acceptance or even journal acceptance. In addition, the current issuance of LoA is still conventional, using paper as the access medium. This is certainly inefficient. In addition, the issuance of LoAs that can be accessed through the website also has certain problems. Many parties doubt the security of the LoA issued through the website, whether confidentiality is really maintained or not. To solve this problem, e-LoA (electronic LoA) was implemented using blockchain technology on the Technopreneurship Journal website. With the use of blockchain technology on this website, LoA data cannot be changed, duplicated or deleted. So that it can improve security and support transparency in the issuance and access of LoA. e-LoA issued through the website also makes it easier for parties to access and download a verified LoA.

Cryptography is known for it's ability to protect confidential information, but it can also be used for other purposes. One of them is for identity verification or authentication. One of the biggest disadvantages of traditional authencation method is at the end of the session, the verifier knows about secrets which is supposed to be known only by prover. In this paper, we implemented a ZeroKnowledge Proof-based secret ticket verification system using Feige Fiat Shamir protocol. The goal of this system is to help prover identified themselves to the verifier, but also prevent the verifier to understand anything about the prover's secret information. The system is also able to prevent ticket duplication or double-use of tickets by using an interactive proof verification method. By combining it with cryptography, not only we can achieve completeness and soundness property of Zero-Knowledge Proof, but we can also achieve information security property.
