My dh works on this, got him to write the following;
Obviously some of the above is related to the Summary Care Record (the 'database') however many of the problems described above exist totally independently of the system. Unfortunately a huge amount of Fear Uncertainty and Doubt has been injected by the misinformed, sensationalist media that make it very difficult to sort the wheat from the chaff on this issue.
It's currently possible to gain access to a medical record via significantly more trivial means than 'hacking a database' - for example simply impersonating an individual at a GP practice requires relatively little skill. With traditional paper-based medical records even receptionists can take a peek at your personal information and you would never know about it.
The care records themselves are stored in secure datacentres, available only via a private NHS network (N3). No system is foolproof of course however there are several other key security mechanisms that have been implemented by central systems.
The system itself has been designed to adhere to the guidelines set out in the Care Record Guarantee which makes a number of pledges to the public regarding treatment of personal data including the provision of the capability for patients to block access to certain personal data if they choose.

All users of the care record service must provide proof of identity (passport or drivers license) and evidence of activity in the community.
Access to all medical records is authenticated with a smartcard - this is fully audited. Unlike other systems it can tell you who has accessed your record with a high degree of certainty.
Only people who have a declared legitimate relationship are able to view a persons care record. Violations of this (in the case where access is required for example, A&E) are notified to the local caldicott guardian (www.dh.gov.uk/en/Managingyourorganisation/Informationpolicy/Patientconfidentialityandcaldico ttguardians/DH_4100563).
Aside from this, there really isn't a viable alternative. Paper-based medical records are prone to loss or theft, unauthorised access and are only available in one location at any time. Further, you will never be able to control who has access to what parts of your personal data with existing systems.
In short, the central systems are significantly more secure than those provided by local NHS organisations including GP practices. I'm not saying it's the answer to everything, and the NHS has a huge amount of other challenges, but I believe it is a step in the right direction.
