When the message transferred from sender to receiver in not added, deleted or modifies by an external third parties, then that message represents the message integrity.
Message confidentiality will be added when the message is not been viewed or noted by the unauthorized user. Message integrity and message confidentiality are related to each other. Without message confidentiality you cannot achieve message integrity and vice versa.
confidentiality keeps the message private Integrity provides the assurance that message has not been altered
Confidentiality, Integrity, Authentication, and Non-repudiationCryptography offers confidentiality and integrity of messages. Confidentiality ensures no one else can read your messages unless they have knowledge of the decryption key. Integrity is knowing the message is unaltered, and can be performed with either a trusted third party, hashing algorithm, or with public key cryptography.
This answer depends on who is sending the information in a secure manner. If confidentiality is required, then the public key of the receiver is used to encrypt the message. If integrity is desired then your private key would be used to encrypt the message.
Message authentication codes
A MAC scheme, short for Message Authentication Code scheme, is a cryptographic technique used to verify the integrity and authenticity of a message. It involves generating a unique tag based on the message content and a secret key, which is then used to authenticate the message and detect any tampering. This provides assurance that the message has not been altered in transit.
Digital signatures are used to ensure that a message was sent by a specific person and that it has not been altered during transmission. They employ cryptographic techniques, where the sender signs the message with their private key, creating a unique signature. The recipient can then verify this signature using the sender's public key, confirming both the authenticity of the sender and the integrity of the message.
Cryptography is used to secure sensitive information by encoding it in such a way that unauthorized individuals cannot access or understand it. It helps protect data confidentiality, integrity, and authenticity in digital communications and transactions.
Cryptography provides security services such as confidentiality (encryption to hide information), integrity (ensuring data hasn't been tampered with), authentication (verifying the identity of parties), and non-repudiation (ensuring a sender cannot deny sending a message).

Confidentiality and data integrity
Yes, a system can provide integrity without confidentiality. Integrity ensures that data remains accurate and unaltered, allowing users to trust the information's validity. However, if the system does not protect against unauthorized access, the data can be viewed by anyone, compromising confidentiality. Thus, a system can maintain integrity while still exposing data to potential breaches of confidentiality.
