Method for Data Storage Protection and Encryption

A method for formatting a disk that includes at least one track and the said track is capable of being divided into at least two geometrical cells (GCs), comprising:

• (a) dividing at least one of the tracks into at least two neighboring geometrical cells (GCs);
• at least one of said GCs defining a different angular size compared to the angular size of a neighboring GC of said track;
• (b) storing Geometrical Cell Location Table (GCLT), for accessing data in said cells, said accessing includes inserting, updating or deleting data.

A method for encrypting data stored in a disk, the disk includes at least one track and track is capable of being divided into at least two geometrical cells (GCs), comprising:

• (a) dividing the disk into tracks and geometrical cells (GCs) constituting sectors and constructing Logical Block Address (LBA), for facilitating access of sector of interest;
• (b) encrypting data in a sector using at least two encryption keys, wherein each key is used to encrypt data in said sector.

A method for encrypting data stored in a disk, the disk includes at least one track and the said track is capable of being divided into at least two geometrical cells (GCs), comprising:

• (a) dividing the disk into tracks and geometrical cells (GCs) constituting sectors and constructing Logical Block Address (LBA), for facilitating access of sector of interest;
• (b) encrypting data in a sector using at least two encryption algorithms, wherein each algorithm is used to encrypt data in said sector.

A method for hindering the possibility of dating data stored in a disk, the disk includes at least one track and the said track is capable of being divided into at least two geometrical cells (GCs), comprising:

• (a) dividing the disk into tracks and geometrical cells (GCs) constituting sectors and constructing Logical Block Address (LBA) for facilitating access of sector of interest;
• (b) storing data in said sectors;
• (c) renewing content of selected sectors according to a predefined criterion, thereby hindering the possibility of dating data based on aging.
