Responsible AI


Limiting access to sensitive AI capabilities

Internal Company Policy: Guidelines for the Use and Management of Internal Enterprise AI Tools

Section 2: Data Confidentiality Classification and Corresponding AI Tool Requirements

In alignment with the Company's Information Security Management System (ISMS), all data classifications strictly adhere to the Company's existing classification framework: Top Secret, Confidential, and Restricted. Employees must select appropriate AI tools based on the corresponding data classification level. Entering any sensitive data into unauthorized tools is strictly prohibited.

Top Secret: Data whose leakage would cause company-wide operational disruption, catastrophic business impact, or unpredictable financial losses. This includes Personally Identifiable Information (PII), encryption keys / API keys, system credentials/passwords, comprehensive core technology and operational decision-making documents, and core trade secrets.

Confidential: Data whose leakage would impair the Company's competitive edge, advantage competitors, or compromise client rights and interests. This includes restricted project documents, non-public internal operational data, financial forecasts, and unannounced partnership initiatives.

Restricted: Data whose leakage would impact localized business operations or cause limited losses without infringing upon individual client rights. This includes system logs, system configuration files, and network/circuit topology data.


Distinct labeling of AI-generated content and outcomes of AI-driven decisions

The Company shall, based on the purpose, risk, technical characteristics, and level of impact of an AI system, disclose its use, primary purpose, capabilities, limitations, potential risks, and applicable conditions in an appropriate and easily understandable manner. When users interact with an AI system, they shall, where appropriate, be clearly informed that they are interacting with AI rather than a human. When the Company provides externally AI-generated text, images, video, audio, or other content, appropriate labeling, disclosure, or identification measures shall be adopted based on the level of risk and context of use. When AI participates in or influences decisions that have a significant impact on individual rights and interests, appropriate explanations shall be provided, including the key influencing factors, basis for judgment, applicable limitations, and methods of human review.

The Company's internal MyBro Assistant clearly states:

"MyBro Assistant is an AI and may make mistakes. | v4.0.0 (BETA)"


Mechanisms to detect and correct drift or degradation of AI models over time

For applications that utilize large AI models provided by overseas vendors, such as GPT and other large language models (LLMs), the Company continuously monitors updates to model service versions and functionalities. Model service providers also continuously optimize and update their models to mitigate the risk of performance degradation over time. When implementing or updating AI models, the Company conducts functional, accuracy, stability, and output quality testing based on the actual application scenarios to verify the suitability of the models for specific business contexts.

Regular assessments of deployed AI models for fairness/bias

The Company assesses the fairness and potential bias risks of AI models based on the intended use of the AI application and the potential impact it may have. For AI applications that may involve individual rights, personalized decision-making, or differential impacts on different users, the Company conducts testing and validation based on the actual application scenarios during initial implementation and model version updates. The testing evaluates whether the model produces results that are significantly unreasonable, discriminatory, or inconsistent with business requirements.

Currently, the Company primarily manages these risks through application-specific testing and validation, rather than conducting abstract fairness assessments solely at the model level. Test cases are designed according to the purpose of each application, and the model outputs are evaluated across different scenarios. If abnormal or unreasonable results are identified, the Company may take corrective measures such as adjusting prompts, application logic, or model versions, or introducing human review. The application is then retested and validated after the corrective measures have been implemented.


Initiatives to lower the ecological footprint of AI data centers/models
  • Empirical Data and Current State Analysis

This innovation enables enterprises to train and run inference on massive 100B to 405B parameter models using standard workstation hardware, drastically reducing high-end GPU resource dependency and energy consumption.


Appeals process for users/affected third parties to contest an AI decision or outcome
  • Empirical Data and Current State Analysis

Taiwan Mobile has established a comprehensive, transparent, and Human-in-the-Loop (HITL) appeal and dispute-resolution mechanism for its flagship AI-driven fraud prediction solution, OP Scam Buster. Leveraging telecom big data and AI models, the system automatically detects and intercepts high-risk phone numbers and phishing URLs to safeguard users. Recognizing that machine learning models inherently carry a margin for false positives, Taiwan Mobile has instituted rigorous remediation and recourse workflows to protect legitimate businesses and benign websites from erroneous classification:

  1. Appeal and Remediation Process for Misclassified Phone Numbers

To safeguard database integrity against arbitrary modifications, phone numbers erroneously flagged as scam, high-risk, or telemarketing require a formal dispute process. The legitimate subscriber must submit an appeal via the dedicated email address (opscambuster@taiwanmobile.com) or by calling the 188 customer support hotline. The process mandates strict evidentiary compliance: applicants must provide the complete phone number, proof of ownership (e.g., subscription agreement or telecom bill), and matching identity documents or business registration certificates. Upon thorough human review and verification by specialized operations personnel, the misclassification is purged from the database and updates are synchronized across client-side applications.

  1. Malicious URL Dispute Mechanism and User-Defined Trust Override:

When a benign webpage is misclassified as a security risk by the AI algorithms in conjunction with the Trend Micro threat database, users or website administrators can submit a dispute via Settings > Feedback within the app. Upon successful manual verification, Taiwan Mobile updates the system-wide whitelist. Furthermore, to uphold the principle of ultimate user agency, the client interface provides an override capability, allowing users to manually designate specific URLs as "Trusted" to directly bypass AI-enforced blocking rules.


Quantification of the impact of AI initiatives/tools on sustainability outcomes

Under the oversight of its ESG Steering Committee, Taiwan Mobile leverages rigorous quantitative metrics to demonstrate the positive environmental (E) and social (S) impacts of its AI implementations:

  • Quantifiable Impact of Intelligent Network and Base Station Energy Conservation
