Methods and systems for secure data storage

A method for storing data in a storage component, the method comprising:

• storing an encrypted version of a first sequence of values in the storage component;
• storing a second sequence of values across a set of non-contiguous memory cells in the storage component, wherein the data comprises a third sequence of values which is derivable from the first sequence of values and the second sequence of values.

A non-transitory computer readable storage medium comprising program instructions stored thereon that are executable by a computer processor to perform a method comprising:

• storing information relating to a first sequence of values in the first storage component;
• storing a second sequence of values from the second storage component into the first storage component in a plurality of steps, deleting or overwriting one or more values from the second sequence of values which were stored in the first storage component in a previous step;
• storing an encrypted third sequence of values in the first storage component, wherein the third sequence of values is derivable from the first sequence of values and the second sequence of values.
