The protection of information from illegal access or disclosure is referred to as confidentiality. Ensuring confidentiality entails ensuring that those who are permitted to access information may do so, while those who are not authorized are barred from doing so. For example, employees should be prevented from disclosing trade secrets, and computers should be secured with passwords.
Confidentiality is also concerned with preventing unauthorized persons from knowing what actions others are taking, such as when there is a legal requirement to keep negotiations secret from competitors. This prevents leakage of information which could give an advantage to others.
Finally, confidentiality is important in order to prevent people from guessing passwords or account numbers and using them instead. This would be undesirable because it would allow unauthorised people access to other people's information.
In conclusion, confidentiality is the action of protecting information by keeping it hidden from view and/or sound. It can be achieved by keeping data on individuals or organizations secretive, inaccessible, or both.
Confidentiality refers to the safeguarding of data against unauthorized access. Data integrity guarantees that no unauthorized changes are made to data, whether deliberate or inadvertent. Authentication ensures that data came from who it claims to have come from.
Encryption transforms plaintext into ciphertext, making it difficult to decode without the proper key. The term "cryptology" comes from the Greek words kruthos meaning truth and logia meaning speech. In mathematics, cryptology is the study of cryptographic systems and techniques.
There are two main types of confidentiality: information-level encryption and file-system protection. Information-level encryption scrambles all the bits of the message equally, whereas file-system protection only scrambles certain bits in a way that doesn't affect how the data is stored on disk. Both methods can be used together to provide additional security. For example, one could use file system encryption to protect sensitive data stored in files that also contain encrypted data.
Information-level encryption transforms all the bits of the message (i.e., the clear text) using a complex algorithm so that only those with authorized access can read the message. All computer programs execute in binary form, which means that they are composed of ones and zeros.
Confidentiality and anonymity are ethical standards used to preserve human subjects' privacy when collecting, analyzing, and reporting data. The separation or modification of any personal or identifiable information given by participants from the data is referred to as confidentiality. Anonymity refers to the fact that no individual can be identified through the use of this information.
Information that is not disclosed by participants but can nonetheless be inferred from available data includes age, gender, marital status, occupation, income, location, size of community, etc. Participants may choose to disclose more sensitive information about themselves, such as abuse histories or psychiatric conditions. In some cases, depending on what questions are asked and how they are answered, information provided by participants may not be considered confidential even though identifying details have been removed. For example, if a researcher obtains a list of names and addresses from a source without first securing permission from everyone on the list, it cannot be assumed that the participants would want their involvement kept secret or that the research project had their best interests at heart. Conversely, if information is provided in confidence and then used in a study that benefits the participant, then the researcher has met his or her ethical obligation.
In conclusion, ethical research involves acting in ways that respect individuals' rights and dignity.
