Automatic age verification using AI complements traditional KYC procedures and increases the speed of verification. Below is a detailed overview of practice in Australian online casinos.

1. Why integrate AI age recognition

Verification speed: instant analysis of the photo instead of manual processing of documents.
Optional Barrier: Serves as a "preventative" level prior to passport/driver's license download.
Risk mitigation: automatic detection of attempts to register minors before the start of the game.
Save resources by reducing the burden on support and compliance.

2. Basic technologies and algorithms

1. Deep convolutional neural networks (CNN)

Architectures (VGG, ResNet) are trained on thousands of age-tagged individuals.
2. Pair Learning Method ("Siamese Network")

Compares the user's face with samples from different age groups.
3. Hybrid models

CNN + facial analysis (wrinkles, cheekbone contours and eyes) + depth metrics (3D modeling).
4. Additional features

Skin color, texture, head shape, hair - are introduced as features to improve accuracy.

3. Integration with traditional KYC

Step 1: the user takes a selfie → AI estimates age in real time.
Step 2: if AI gives a chance <18 years → the system requires an official document to be downloaded.
Step 3: Documents are processed via DVS and banking APIs (ACIP).
Step 4: AI and DVS results are compared, if the same age is confirmed.

4. Accuracy, limitations and errors

Parameter	Value/Range
Mean absolute error (MAE)	2-3 years
18 + accuracy	95-98%
Main sources of errors	unusual makeup, glasses, masks
Retest requirement	if AI vs document difference> 4 years

False Positive (under 18): blocks adults → tough policy "better double-check."
False Negative (over 18): potential admission of minors → retest through the document.

5. Compliance and data protection

1. Privacy Act 1988 and GDPR-like norms

Saving biometrics only for the duration of verification, without long-term storage.
Encryption of images and check logs.
2. Interactive Gambling Act 2001 и ACIP

AI serves as an auxiliary tool, final verification through the required ACIP documents.
3. Transparency and auditing

Mandatory logging of AI solutions, access to regulators during checks.
Regular external audit of models for absence of displacements (bias).

6. Practical cases of leading platforms

Bet365 AU: implemented an AI module before downloading the document, reduced verification time by 40%.
Sportsbet: hybrid AI + DVS, "gray" age (16-20 years) automatically goes for manual verification.
PlayUp: Having abandoned "subsequent" verification, they now require selfies and conduct AI screening before deposit.

7. Implementation Recommendations

1. Provider selection

Evaluate the MAE and AUC of the models, check the bias reports by ethnic group.
2. UX Optimization

Minimize clicks: selfies → instant response → dock loading only when needed.
3. Testing and training of models

Periodically update the training dataset taking into account local features and new visual trends.
4. Hybrid approach

AI screening + traditional KYC to bridge the weaknesses of each technology.
5. Monitoring and auditing

Implement a dashboard to track key metrics (MAE, FPR, FNR) and review regularly.

Result

AI age recognition in online gambling is an effective additional layer of tolerance protection <18 years. The combination of deep neural networks, DVS-API and banking KYC allows you to speed up verification, reduce the workload on personnel and ensure compliance with the law, while observing the requirements for privacy and transparency.
