Pixel Value Graphical Password Scheme

Pixel value access control (PVAC) was introduced to deliver a secure and simple graphical password method where it requires users load their image as password. PVAC extracts the obtain three-octet 8-bits Red-Green-Blue (RGB) its authenticate user. The pixel must be matched with record stored in database or otherwise, user is failed authenticate. However, which prefer store images on cloud storage would unintentionally alter well due media compression caused faulty pixels. Thus, K-Means clustering algorithm adapted fix issue recognized having same cluster original. most of works were mainly developed for content-based retrieval (CBIR) opposite characteristics from PVAC. this study aimed investigate crucial criteria compatibility problem. theoretical analysis used suitable are analyze based requirements. compliance might become referencing work digital techniques adaptation security system such filtering, recognition, object detection since focused less sensitive retrieval.
