Keamanan sistem informasi pada saat ini telah banyak dibangun oleh para kelompok analis dan programmer namun pada akhirnya ditinggalkan oleh para pemakainya. Hal tersebut terjadi karena sistem yang dibangun lebih berorientasi pada pembuatnya sehingga berakibat sistem yang dipakai sulit untuk digunakan atau kurang user friendly bagi pemakai, sistem kurang interaktif dan kurang memberi rasa nyaman bagi pemakai, sistem sulit dipahami interface dari sistem menu dan tata letak kurang memperhatikan kebiasaan perilaku pemakai, sistem dirasa memaksa bagi pemakai dalam mengikuti prosedur yang dibangun sehingga sistem terasa kaku dan kurang dinamis, keamanan dari sistem informasi yang dibangun tidak terjamin [1].
Hal-hal yang disebutkan diatas dapat disimpulkan bahwa dalam membangun sebuah keamanan system informasi harus memiliki orientasi yang berbasis perspektif bagi pemakai bukan menjadi penghalang atau bahkan mempersulit dalam proses transaksi dan eksplorasi dalam pengambilan keputusan. Terdapat banyak cara untuk mengamankan data maupun informasi pada sebuah system [1].
Seiring dengan perkembangan teknologi informasi, pemalsuan dan penyelewengan dokumen sering kali terjadi terutama dokumen-dokumen cetak, sedangkan kita tahu bahwa dokumen merupakan salah satu data yang sangat penting, sebab dokumen merupakan sumber informasi yang diperlukan oleh instansi, organisasi, negara serta individu. Penggunaan barcode tidak asing lagi di industri di seluruh dunia [2]. Hal ini untuk memudahkan pelaku industri dalam menjalankan usaha yang dimilikinya, sebab barcode ini menyimpan data spesifikasi seperti kode produksi, nomor identitas, dll sehingga sistem komputer dapat mengidentifikasi informasi yang di kodeka dalam bentuk barcode dengan mudah. Seiring dengan perkembangan dan kebutuhan penggunaan barcode digantikan dengan QR code [3].

Some administrative procedures in many institutes are still carried out conventionally, which is deemed less efficient and takes much time. On the other hand, communication with other parties requires a process of exchanging information, so a system is needed to confirm the validity of the information. Therefore, a digital letter system that can prove the validity of the information gained through the digital media right from the party concerned is developing. This can be overcome using the authentication method. Adding One Time Password (OTP) as an authentication method that employs one temporary password key can be the solution. This study uses the One Time Password (OTP) method as a validation system and the SHA-512 algorithm as an OTP code generator to generate random codes. This system leverages android technology on mobile to ease access to the correspondence administration system to make it easier to visit with features that prioritize information and access speed. This application is implemented at the State Polytechnic of Sriwijaya to improve the administrative process to run more effectively. The black box testing revealed that all available menus and features were appropriate, and the application already had a system that functions according to user needs. Moreover, in the One Time Password generation test with the SHA-512 algorithm, it was determined that the average response time for generating the OTP code was 4.4 seconds in 15 trials, which can be considered fairly accurate.

A previous study has been conducted integrating modification on secure hash algorithm 1 (SHA-1) to document integrity verification of printed documents using quick response (QR) codes. However, encryption is warranted as data is transmitted in plaintext directly to the server to prevent hacking and ensuring not only data integrity but data security as well. A more secured document integrity verification using QR code was designed and developed by successfully incorporating a better hashing algorithm– modified SHA-1 and integrating a modern encryption algorithm–modified blowfish algorithm. By integrating both, data integrity and data confidentiality is assured as compared to previous research. The developed software was checked against user requirements to check the acceptability of the software. Error rate and accuracy were also checked to see how the software performed. Based on the testing conducted, it has been found that the document integrity verification software using QR code with the integration of modified SHA-1 hash and Modified Blowfish encryption was acceptable, accurate, and more secure.

Paper-based documents or printed documents such as recommendation letters, academic transcripts, and diplomas are prone to forgery. Several methods have been used to protect them, such as watermarking, security holograms, or using paper with specific security features. This paper presents a document authentication system that utilizes QR code and ECDSA as the digital signature algorithm to protect this kind of document from counterfeiting. A digital signature is a well-known technique in modern cryptography used for providing data integrity and authentication. The idea proposed herein is to put a QR code in the printed documents where the QR code includes a digital signature. The signature can later be authenticated using the proposed system by uploading the document for authentication or scanning the document's QR code. The proposed system is particularly developed for digital signature generation and verification of students' final project approval documents as the case study. In traditional settings, the approval form is typically signed directly by the student's advisor dan co-advisor using handwritten signatures. However, using the conventional handwritten signature, the signature on the approval form can be falsified. Therefore, a digital signature generation and verification system is implemented herein to avoid handwritten signature falsification. The advisors can use this system to sign the approval form using a digital signature instead of a handwritten one. The signature is stored in a QR code and is generated using ECDSA with SHA-256 as the hash function. The proposed system is evaluated using documents (i.e., approval forms) with genuine and forged QR codes. The evaluation results showed that the system could verify the authenticity of the approval forms, which contain genuine QR codes. The approval forms that contained forged QR codes were correctly identified.
