Abstract
A method for protecting seed data according to an access hierarchy is disclosed. A seed data entity is resolved into a plurality of seed data units each having an associated protection level and customization level. When a request to modify a seed data unit is received, an access level is determined for the request. The seed data is modified in accordance with the request if the access level determined for the request is superior or equal to the protection level of the seed data unit and inferior or equal to the customization level of the seed data unit. If the seed data is modified or replaced, the access level determined for the request is assigned to the customization level of the seed data unit.
