Personal data can be held only for specified
and lawful purposes
The Data Controller has to state why they want to collect and store
information when they apply for permission to be able to do so.
If they use the data they have collected for other purposes, they
are breaking the law.
Personal data should be adequate, relevant
and not excessive for the required
Organisations should only collect the data that they need and no
more. Your school needs to know your parent's phone number
in case they need to contact them in an emergency. However,
they do not need to know what your grandmother's name is, nor
do they need to know your eye co lour. They should not ask,
nor should they store such details since this would be excessive
and would not be required to help with your education.
Personal data should be accurate and kept
Companies should do their best to make sure that they do not record
the wrong facts about a data subject. Your school probably asks
your parents to check a form once a year to make sure that the
phone number and address on the school system is still
correct.If a person asks for the information to be changed, the
company should comply if it can be proved that the information
is indeed incorrect.

later on. However, there is no need for a personnel
department to keep the application forms of unsuccessful

be taken against unauthorised access

and employees who don't have rights to see it. Data must
also be safeguarded against accidental loss.
Personal data cannot be transferred to
countries outside the E.U. unless the
country has similar legislation to the
This means that if a company wishes to share data with an
organisation in a different country, that country must have
similar laws to our Data Protection Act in place.
