Through the Transparency Report, Kakao shares with users the status of its responses
to the government's request for data based on the necessity for warrants in a
transparent manner.

The Meaning of the Transparency Report

Transparency Report refers to a statistical report outlining the government's requests for personal information and corporate responses thereby. The fact that companies transparently disclose how they respond to government's requests has great significance in terms of protecting user rights.

Communication data

User name, resident registration number, address, telephone number, ID, and subscription/withdrawal date are classified as "communication data," according to the Telecommunications Business Act. Courts, prosecutors, and investigative agencies may request communication data when necessary for criminal investigations, executions, and trials. Kakao does not provide any communication data currently reflecting the decision of the Constitutional Court (2010 Heonma 439) that the government's request for communication data has a legal basis but is not a mandatory requirement.

Communication-restricting measures

Communication-restricting measures often refer to wiretapping telecommunications. According to the Protection of Communications Secrets Act, communication-restricting measures shall be used as a supplementary means of facilitating a criminal investigation or ensuring national security, and efforts shall be made to minimize the violation of people's communication secrets. Kakao has stopped cooperating with communication-restricting measures since October 2016 following the Supreme Court's decision [2016 Do 8137] that there is no admissibility of evidence if it is not real-time wiretapping of telecommunication under the Protection of Communication Secrets Act. However, in the case of Daum services, Kakao provides part of its data after a thorough review pursuant to legal standards.

Communication confirmation data

The other party's subscriber number, log record (date/time), IP address, etc. are classified as communication confirmation data under the Protection of Communication Secrets Act. Investigation agencies shall request data by permission of courts, including request reason, relevance to the requested user, and the scope of required data.

Warrant of seizure and search

Warrant of seizure and search refers to a compulsory investigation conducted by an investigation agency to find evidence against a suspect and is issued by courts upon request of the prosecutor. The warrant includes items to be confisticated or places to be searched. In case of telecommunications, it includes specific periods to be investigated.

Principles and Procedures

Kakao first reviews the legality of such a request upon the government's request for personal information. Based on the legal requirements, Kakao responds to the government requests in the following five steps:

  • Reception

    Judicial agencies, such as the prosecution and the police, submit necessary documents to Kakao.

  • Document Validation

    Kakao shall meticulously check legal requirements for the submitted document (e.g. recipient, official seal, seals between pages, approval authority, documentary requirements, identity verification of investigation officers, etc). If the above application fails to fulfill the requirements, Kakao sends back a reply, including reasons for rejection. If the above application fulfills the requirements, Kakao goes through the procedures for processing documents.

  • Processing

    Kakao stringently selects only the parts that can be provided under laws and internal policies to ensure a user's privacy, even if the received documents meet all requirements. The person in charge who has been granted limited search authority encrypts the requested data so that no one other than the judicial investigator in charge can view such data.

  • Review

    The person in charge thoroughly reviews how the documents have been processed.

  • Reply and retention

    Any information provided to judicial authorities among the requested data will be destroyed in a way that cannot be immediately recovered once the purpose of the reply has been completed.

Transparancy Report FAQ

Transparency Report refers to a statistical report outlining the government's requests for personal information and corporate responses thereby. The name signifies that the company transparently discloses to users how it responds to government's requests. Kakao will continue to exert its utmost efforts to protect users' rights and disclose the results in the transparency report.

Upon any request from a judicial authority, Kakao shall properly respond to such requests in due process based on the necessity for warrants, and disclose related matters in the transparency report. We believe that we are, as a member of our society, under the obligation to faithfully fulfill legal requirements, and that it is our responsibility to build trust with users by transparently disclosing related matters so that anyone can look up. Kakao is committed to fulfilling its duty of mutual trust between the company and users by updating the transparency reports twice a year. Kakao Transparency Report shows our firm determination to protect users' rights and our confidence that we stringently comply with due process to secure users' information. Kakao will continue to respond to the government's requests in accordance with legal regulations and share the status with our users in a transparent manner.

There is no fixed framework to prepare a transparency report and it may differ among companies. Mostly, a transparency report shares the status of the government's requests and the company's response. Kakao Transparency Report contains status data on government requests for personal information and Kakao's response thereby. We believe that our bi-annual disclosure will be the cornerstone of counterbalancing public security and individual privacy in our society.

Kakao does not directly respond to such requests from a foreign government, judicial authority, or private institution. They must, if necessary, request cooperation from the Korean government and judicial authority. Also, Kakao does not deal with a request from private institutions that have not fulfilled procedural formality.

Kakao Transparency Report uses three types of statistical figures: the number of government requests, the number of cases processed, and the number of accounts. The number of requests and the number of cases processed are based on the number of documents submitted by investigative agencies. The number of requests means the number of documents requested by the government, whilst the number of cases processed refers to the number of documents provided upon the government's request. The number of accounts means the combined numbers of accounts (ID and/or phone number) processed upon request and related accounts.

Kakao responds to a request from judicial authority only if the documents meet all legal requirements. If documents submitted by the government fail to meet the legal requirements, we do not provide any personal data. That is when statistical difference may occur - the number of cases processed is less than the number of requests.

In principle, Kakao does not provide any personal information without consent from the user. However, if a case falls under exceptions stipulated in relevant laws, a part of personal information may be subject to the provision. Explicitly, the Personal Information Protection Act sets it as an exception if otherwise specified by other laws.

Kakao selectively responds to the government's request for the provision of personal information, only when it is subject to legal obligation. The laws that provide the basis for reviewing the legitimacy of government requests are as follows:

(1) Protection of Communications Secrets Act (Communication-restricting measures and communication confirmation data)

Service providers shall not disclose or divulge the fact that an investigation agency has requested to provide information pursuant to the confidentiality obligations of the Protection of Communications Secrets Act. According to the Protection of Communications Secrets Act, when a public prosecutor or a judicial police officer has executed confiscation, search, investigation or communication-restricting measures or has been provided with communication confirmation data, regarding telecommunications of which the transmission and reception had been completed, he/she shall be obliged to notify the object of such fact. Any prosecutor or judicial police officer thereby shall, when he/she institutes a prosecution or takes a disposition not to institute any prosecution or indict (excluding any decision made to suspend any indictment), notify in writing the person subject to such disposition of the fact that the warrant is executed, the institution that executes such measures and the period thereof within 30 days. Therefore, any information offered to an investigation agency can be confirmed by a competent prosecutor or judicial police officer.
