Interesting to see #LinkedIn stepping back from slop production because it turns out customers hate it. (Also give the writer a medal for the description of AI tweaking of text). www.theregister.com/ai-and-ml/20...

Screenshot of quote from TheRegister.co.uk: “In addition, the "enhance your post" button, which used AI to tweak your wording, is being replaced by an option to have AI proofread your work while leaving your voice intact, instead of stealing it like the sea witch Ursula.”

So let’s look at how the processing is described in the @dpcireland.bluesky.social decision of 9th June 2025. Oh look. “Biometric template” used for “one to many” and “one to one” matching. If it walks like a duck and quacks like a duck we might just have a bird of the genus Anatidae on our hands.

Screen shot from DPC decision. It reads:
28. The Cogent Facial Image Matching System ("CFIMS") feature extraction (also referred to as "template generation" and "template creation" analyses the facial image and generates a numerical representation of the face. This numerical representation is the biometric template that then represents the features and characteristics found on the
The templates are processed
using a matching algorithm
which compares
biometric templates to compute a matching score. In a facial recognition context, this score represents a measurement of the likelihood that two separate images refer to the same person. CFIMS compares the template it creates from a new facial image with the other templates already held by the DSP. This is referred to as "one-to-many matching".
29. Where a data subject already holds a PSC and seeks to renew it, they can update the photograph of their facial image online (up until March 2020, they could also do so by post). 6 This is in turn subject to a similar process, whereby the template is subjected to one-to-many matching and in addition is compared against the previous template held in relation to the same data subject. That is, the new template is matched against the previous template. This is referred to as "one-to-one matching".

So, as the X press office on Fenian Street work to move the problem on to a different parish, it’s worth checking the definition of the word “connive”, as in “connivance”.

A fun evening out for the opening night of #Wexford #Panto. Hard to believe it’s over 5 years that @castlebridge.bsky.social has been sponsoring this fantastic production put on by a dedicated team of volunteers and local performing arts groups. www.wexfordpanto.com Worth every penny.

This is the form organisations need to fill out www.forms.gov.ie/en/689ef1450.... It's all good stuff for organisations to aspire to, and Commitment 6 is a good one for supporting circular economy (Just remember to reset devices to factory settings and wipe all data before recycling them on.)

And boy I love the AI Slop background image as I wait (now 35 minutes) for the verification code to land.

Photo of IAPP website with borked account confirmation process and, more painfully, a bizarre abstract background image that is likely AI generated as it lacks any coherence of design or concept. It’s a green background with shields and faces and keys and other nonsense. I won’t waste your time trying to describe it further.

Also: selection of NACE code is mandatory for a business, but there are only 17 entries and one of those is “Private Household with Employed Persons”. Nothing like “Business or other Management Consulting Services (NACE70.22). So, that data will be useless for any form of reporting.

Photo of employer registration screen for MyFuture Fund. The requirement is to “please select the NACE code as used for your company’s registration in Ireland”. A drop down list is shown. It has 17 entries to choose from. The options don’t actually match NACE codes and there is no option for “Business Services” or “Management Consulting”

Minor correction: It’s Section 3(4) of the Road Traffic Act

Here’s the slide pack from the time I got the late #LarryEnglish to do an Information Quality Masterclass in Dublin back in 2006. In March next year I’ll be helming another #DataLeaders Summit in Wexford (summit.castlebridge.info).

Doing a tidy in my office at home (instead of doing the research that was scheduled today). Found this from almost 16 years ago. I did two talks at this conference. One on #DataQuality and #DataProtection and another on #DataQuality and #Strategy. Content still 100% relevant today!

Cover of a conference pack from 2009. The title of the conference was “Developing Best Practice for information and data quality management”

Bluntly: this is illegal. It violates a very fundamental principle in #GDPR and in #DataGovernance - separation of duties / independence of DPO. There’s case law and extensive guidance on this principle under GDPR

Extract from EDPB guidance on role of DPO. Text reads:
“The absence of conflict of interests is closely linked to the requirement to act in an independent
manner. Although DPOs are allowed to have other functions, they can only be entrusted with other
tasks and duties provided that these do not give rise to conflicts of interests. This entails in particular
that the DPO cannot hold a position within the organisation that leads him or her to determine the
purposes and the means of the processing of personal data. Due to the specific organisational structure
in each organisation, this has to be considered case by case.
As a rule of thumb, conflicting positions within the organisation may include senior management
positions (such as chief executive, chief operating, chief financial, chief medical officer, head of
marketing department, head of Human Resources or head of IT departments) but also other roles lower
down in the organisational structure if such positions or roles lead to the determination of purposes
and means of processing. In addition, a conflict of interests may also arise for example if an external
DPO is asked to represent the controller or processor before the Courts in cases involving data
protection issues.”

So, this is how the holder of the post of Information Commissioner in the U.K. response to a valid comment by a highly respected #DataProtection expert when invited to comment on “what does privacy mean to you”. Not exactly the kind of response you’d expect.

Screenshot of a LinkedIn post by Jon Baines responding to an ICO post about their undertanding of Privacy. Jon is pointing out that Privacy is not actually what the Commissioner regulates, rather it’s Data Protection.

Screen shot of the response to Jon Baines comment by John Edwards, the UK’s Information Commissioner.

One word: “Yawn”

Obviously this sparked some reaction from data protection practitioners on LinkedIn

I occasionally look at the cookie banner behaviour of sites that people *have* to use. This is the site of Ireland’s National Car Testing Service. It pre-ticks boxes for consent (illegally) and then you can’t actually set those choices and have to click accept to move on (invalid consent). #GDPR
