1.ABSTRACT

A cloud-based e-KYC system provides a more efficient and flexible authentication method compared to the host based e-KYC authentication method where documents need to be validated via the centralized host. Essentially, the security and privacy of e-KYC related documents stored in the cloud becomes the crucial issue. Existing e-KYC platforms generally rely on strong authentication and apply traditional encryption to support their security and privacy requirement. In this model, the KYC system owner encrypts the file with their host's key and uploads it to the cloud. This method induces encryption dependency and communication and key management overheads. In this paper, we introduce a novel blockchain-based e-KYC scheme called e-KYC Trust Block based on the ciphertext policy attribute based encryption (CP-ABE) method binding with the client consent enforcement to deliver trust, security and privacy compliance.
