Abstract

Easy and efficient access to banking services is essential for customers in the digital era, including those of rural banks such as BPR. BPR Saraswati Eka Bumi currently does not offer a mobile banking application, causing customers to rely on manual processes for opening accounts, saving, applying for loans, and placing deposits. In response to this issue, a mobile application interface was designed to support the digital transformation of BPR Saraswati Eka Bumi's services. The design process adopted the design thinking method, consisting of five stages: empathize, define, ideate, prototype, and test. Through these stages, key features were developed including online account registration, SiMaPan savings, loan application, and digital deposit services. The resulting interface prototype was tested internally and received positive feedback regarding its usability and clarity. This design is expected to serve as a reference for the future development of BPR Saraswati Eka Bumi’s official mobile banking application.

Abstract

In the digital era, securing sensitive information such as seed phrases are crucial to prevent unauthorized access and potential loss of digital assets. This paper proposes a novel approach for protecting seed phrases using dual-layer encryption with AES algorithm and Caesar cipher. The AES algorithm is utilized to encrypt the seed phrase itself, providing a strong first layer of defense. Additionally, Caesar cipher is employed to encrypt the AES secret key, adding an extra layer of security to the encryption process. By combining these two encryption techniques, the security of the seed phrase is significantly enhanced, as both the phrase and its encryption key are protected. Furthermore, the encrypted seed phrase and key can be securely stored using email as a digital storage medium, enhancing accessibility while maintaining robust security measures.
