The security and privacy of medical documents containing sensitive information about patients is of utmost importance. Encryption is a critical aspect of protecting these documents from unauthorized access, and the nearest neighbor search scheme is a promising method for improving the encryption process. This paper presents a detailed analysis of the use of the nearest neighbor search scheme for the encryption of medical documents. The nearest neighbor search scheme involves dividing the medical document into blocks and generating a key by applying the scheme to a database of documents. The key is used to encrypt and decrypt the document, making it difficult for attackers to access the confidential information. The scheme is highly efficient, requiring only the calculation of the cosine similarity between documents in the database, making it suitable for use in resource-constrained environments. The paper discusses the benefits of the nearest neighbor search scheme in the context of medical document encryption. The scheme provides a high level of security by generating a key from a random document in a large database, which makes it difficult for attackers to guess the key. The scheme also ensures efficient encryption and decryption because it does not require a large amount of computational power. The use of the nearest neighbor search scheme for the encryption of medical documents is a promising approach that can improve the security of these documents. Further research can be conducted to optimize the scheme for different scenarios. For example, the scheme can be optimized for use in scenarios where the database is limited, or where the medical documents have specific characteristics that may affect the performance of the scheme. The paper highlights the need for continued research to optimize the scheme and improve its effectiveness in different settings
