PROTECT, RESTRICTED and CONFIDENTIAL, however this is not the case, since the criteria on which GPMS markings were applied bear no relationship to the criteria used for GSCP classifications. It is quite possible, and not uncommon, for data within an OFFICIAL classification to have serious impacts including serious injury in the event of unauthorised disclosure. This is one of the characteristics of the GSCP which differs significantly from the Protective Marking Scheme which it replaced. At the OFFICIAL classification there is a general presumption that data may be shared across Government, however where a need to know principle is identified data may be marked as "OFFICIAL-SENSITIVE"; "OFFICIAL-SENSITIVE COMMERCIAL"; "OFFICIAL-SENSITIVE LOCSEN" or "OFFICIAL-SENSITIVE PERSONAL". All OFFICIAL-SENSITIVE data must be marked and contain handling instructions identifying why the data is deemed sensitive, how it must be held, processed and transferred. Government Protective Marking Scheme The older system used five levels of classification, supplemented with caveat keywords. The keyword was placed in all capital letters in the centre of the top and bottom of each page of a classified document and described the foreseeable consequence of an unauthorised release of the data (a ‘breach of confidentiality’). In descending order of secrecy, these are: TOP SECRET Information marked as TOP SECRET is that whose release is liable to cause considerable loss of life, international diplomatic incidents, or severely impact ongoing intelligence operations. Prior to the Second World War, the highest level was "Most Secret"; it was renamed so that both the UK and U.S. operated to a consistent system. SECRET This marking is used for information whose side-effects may be life-threatening, disruptive to public order or detrimental to diplomatic relations with friendly nations. CONFIDENTIAL The effects of releasing information marked as CONFIDENTIAL include considerable infringement on personal liberties, material damage to diplomatic relations, or to seriously disrupt day-to-day life in the country. RESTRICTED Information marked as RESTRICTED is at a level where the release of the material will have effects such as significant distress to individuals, adversely affecting the effectiveness of military operations, or to compromise law enforcement. PROTECT Such information will cause distress to individuals; cause financial loss or improper gain; prejudice the investigation of, or facilitate the commission of, a crime; or disadvantage government in commercial or policy negotiations with others. PROTECT should always be used with a descript such as “Commercial”, “Management”, “Personal”, or a similar term. UNCLASSIFIED The term "UNCLASSIFIED"
