SCSC Post Office Horizon Position

* The Post Office Horizon system would not normally be regarded as a safety system, yet it is a computer-based system that has indirectly led to widespread harm.

* The ongoing public enquiry has raised important legal, ethical and technical concerns. Problems highlighted include: sub-postmasters could not see what was going on (for example, figures changed remotely without sub-postmaster knowledge), poor quality coding and lack of both audit and fault logging.

* The SCSC fully supports the public enquiry and other investigations, and we agree with professional computer bodies (e.g. the British Computer Society) that there should be a review of how computer-based system evidence is treated by the courts.

* We will look to adopt relevant recommendations and encourage our members to do the same once the enquiry and investigations conclude.

* We propose that organisations relying on computer-based system evidence in court should, where challenged, be required to justify that the system, including aspects such as hardware, software, data and service delivery, is reliable. Furthermore the evidence should be shown to be trustworthy. The justification should also show appropriate confidence in use, including in the way that reported problems are managed. Courts should not accept evidence relating to the computer-based system without this justification.

* Where there are disputes involving computer-based systems there must be fair treatment; i.e. where relevant, there must be access for both sides to technical experts who in turn must be given access to appropriate software and data.

* Post Office Horizon is an example of how systems, organisations, agreements, people and processes came together within a delivered service to result in indirect but severe harm. We suggest that the SCSC Service Assurance Guidance could be useful in such situations to reduce risks.

* We will extend the remit of the SCSC to cover any computer-based systems and services which could cause harm. This will include harm in the wider context of the system including all stakeholders, the environment and consequential harms, not just harm caused directly by the system or service itself.

Note: Here “computer-based system” includes aspects such as hardware, software, data and service delivery. 

AI Investment

Microsoft is opening a new office in London dedicated to artificial intelligence (AI) research and development: https://lnkd.in/e7BVeV-N
This technology is going to impact us in so many ways - the SCSC will look at some of the safety implications in a series of seminars this year. The first seminar looking at frameworks is on 25th April: https://scsc.uk/e1081

The IET has announced the Young Women Engineer of the Year Awards 2023, https://youngwomenengineer.theiet.org

Time Set for National Mobile Phone Emergency Alert Test (Apr 23)

On Sunday 23rd April 2023 at 3pm UK time there will be a test of the national mobile phone emergency alert system which should send a message to about 90% of phones in the UK. In the future true alerts could be more localised to a specific area. This could be a very useful system. Any info about how it is being implemented, and presumably assured, would be appreciated. mike.parsons@scsc.uk
