Abstract
Data security is currently the theme tackled in many areas and not just at the high level of the security. These are not only a bank or a state institution, where the need is to protect sensitive information and nance.
We all have become accustomed to using multifactor security (user ID, password, password sent by sms, ...), when we access from the comfort of our home to our internet banking or when we perform payment transactions. No one minds access to his/her computer or the corporate network using a combination of multiple types of security (user name, password, ngerprint, ...).
We note, however, that not only the information which the authorities have about us (name, date of birth, social security number, identity card number, address of permanent or temporary residence, entries in the registry of punishments, details of the employer records, entries from the business, trade or insolvency registry, entries from the land register ...) and nancial institutions (exact data on the heights of revenue and expenditure, information on various types of insurance, ...), but also information which the doctors and medical facilities have about us (medical history, operations, allergies, permanent consequences, ...) need to be protected.
