SK ID Solutions declared provider of vital services

1 Reply

The Identity Documents Act was amended declaring the provider of certification services a vital service provider:

(31) The provider of certification service that enables digital identification and digital signing with the certificate which is entered in the documents issued on the basis of this Act is the provider of vital service specified in clause 36 (1) 8) of the Emergency Act.
[RT I, 03.03.2017, 1 – entry into force 01.07.2017]

In practice, at least currently the new status does not introduce significant new requirements, since for SK as a qualified trust service provider the operational requirements set by law were quite high anyway.

Personal data tracker service allows to infer activities of other persons

Leave a reply

From the March of this year everyone is able to check on the eesti.ee portal, which state agencies have reviewed their data from the population register. The new service is a matter of grave concern to notaries who are required to make inquiries into the population register, for example, if it is necessary to find out whether real estate may be the joint property of spouses or former spouses, or if it is necessary to organize succession proceedings based on data, including identifying potential heirs. According to Eve Strangi, Chief Executive Officer of the Chamber of Notaries, after the Data Tracker service came into being, people who did not use the notarial service themselves, but whose parents, children or spouse had done this, also came to the notice that personal data was viewed.

In most cases, people can get information that their data has been viewed, but not always. “An exception, for example, is the situation where heir data is required to make a will. However, the will until the death of the maker is secret, and the existence and content of the act can not be disclosed to the heir earlier than specified by the law.

Heiko Vainsalu, Head of the State Information System Agency X-Road, said that the Data Tracker highlighted weaknesses in information systems, which should now be addressed by the authorities themselves. “It is now up to the authorities to eliminate them – to improve the logic of data services and to find data services better suited to specific needs. Besides the ability to track the use and processing of the data in the state information system, the Data Tracker helps to highlight and correct the design mistakes of information systems.”

Some filters are needed. For example, the queries made by law enforcement institutions in investigating the crimes must not show up to the subjects in the Data Tracker service.

Possible to apply for new ID card online using bank authentication

Leave a reply

The Police and Border Guard (PPA) have a new online portal where citizens can apply for ID cards based on previously issued identification. Beyond their existing ID cards, people could also log in using their Mobile ID or Internet bank, which is good news for Apple users, as the state’s systems typically don’t work to the full extent for anyone coming in using Apple devices. That people could use their bank to log in meant that also those could apply for a new ID whose existing one had already lost its validity, Abram added.

The solution likely to be very welcome, as PPA has limited the number of offices where people can apply for documents to just a handful of service centers, and queues have been a constant problem. There are plans to extend the portal’s services to include passport applications as well other processes that are currently limited to PPA’s service centers, and to include all residents of Estonia that have a personal identification code (isikukood).

The law was changed to remove the requirement for the application to be digitally signed:

§ 5. Electronic filing of application
(1) Upon submission of an application electronically, the documents specified in the Regulation shall be attached to the application electronically.
(2) An electronically filed application shall be signed digitally or submitted uniquely via an electronic channel that allows verification of identity.
(3) If an application is submitted via an electronic channel specified in paragraph 2, the applicant shall, upon issuing his identity document, confirm with the signature that the data and documents submitted by him in the application are correct.

Sensitive personal data published in document registers of state agencies

Leave a reply

During a Garage48 hackathon held in Tallinn over the weekend, one participating team announced that they could not publish the results of their work as it contained too much personal data they had accidentally come across in state document registers. There are hundreds of such registers across Estonia, as each ministry, agencies, local governments and schools all have their own digital document registers.

The paper noted that while the Estonian Data Protection Inspectorate does check the security of document registers, it does so by hand, and checks are often followed by monitoring procedures and, less frequently, even fines for register administrators.

A similar problem was discovered back in April by Estonian startup Texta that created its own document registers analysis tool. Co-founder of Texta Silver Traat said they discovered a lot of highly detailed personal information in the documents register of the education ministry.

„We held a workshop as part of a language technology conference where we did what the state lacks the capacity to do itself. We downloaded 150,000 documents from the ministry’s document register and discovered that they held, among other things, people’s personal identification numbers, bank account numbers, addresses. We even came across some passport numbers,“ Traat described. He added that most of the information was from employment contracts.

This is the unfortunate side-effect of open data. For that data to be useful it actually has to contain at least some bits of personal data.

Estonian “data embassy” to open in Luxembourg

Leave a reply

Data of the Estonian administration may be stored on servers in Luxemburg as well as in Estonia already towards the end of this year. The “data embassy” created this way will contain information vital to the functioning of the state, and make an attack on the country’s systems more difficult.

As cyber security expert of Tallinn’s NATO Cyber Defence Centre of Excellence, Jaan Priisalu, says, “If an operator is planning to occupy another country, one of their objectives is going to be to take over the existing institutions, or to suppress them, and if you can make these institutions ex-territorial, take them out of reach of the potential attacker, you increase the political price of the attack.”

According to advisor to the ministry’s state information systems department, Laura Kask, negotiations were held with other countries as well, but the ones with Luxembourg had developed the furthest. “For one thing, they offer data centers with a very high level of security, and for another they are quite similar to us in terms of their IT development and their way of thinking,” Kask said. In terms of money, there are no exact figures available, but the data center in Luxemburg will be markedly more expensive than running a similar infrastructure in Estonia. There is one entry in the government’s schedule concerning the data embassies, showing an allocation of €240,000.

The physical location of the servers will remain secret, and only people will have access to them that are cleared by the Estonian state.

The data to be backed up in Luxembourg so far covers ten priority databases, including the information system of the Governmental Payments Office (the Estonian treasury), the pensions insurance register, the business register, the population register, the cadaster, and the identity documents database.

Even now nothing forbids Estonian state to store data backups in Estonian embassies located in foreign states. Most likely the plan is to build failover system that is kept in sync in real time.

Oberthur will produce Estonian ID cards from 2019

Leave a reply

id_card_blank

The Police and Border Guard Board (PPA) and French company Oberthur Technologies signed an agreement on Thursday for the production of Estonia’s ID cards, permanent resident cards, digital IDs and diplomatic IDs after the current manufacturer agreement expires at the end of 2018.

Oberthur Technologies will be responsible for the manufacture of the card and chip as well as and linking the document to personal data. It will also be responsible for the functioning of the card. The French company will manufacture and personalize the cards in Estonia.

The value of the five-year contract is approximately €40 million. Under the new agreement, the expenses of the PPA for the manufacture of the ID card will remain at the present level.

A tender committee, which in addition to PPA experts included experts from the Estonian Information System Authority, the Ministry of the Interior and the ministry’s IT and Development Centre, chose the offer by Oberthur from among three different offers.

This was already the second tender. In the first tender Safran Morpho was chosen as the winner. The results of the first tender were appealed by two other participants – Oberthur Technologies and Gemalto/Trüb AG. The result of the appeal was that the current contract with Trub AG was prolonged for one more year.

In a public procurement tender of the Estonian Police and Border Guard Board three renowned European ID producers submitted their offers. The tender committee chose the offer of Safran Morpho as the winner, the Police and Border Guard Board said.

The German company Trub AG, which last year was acquired by Gemalto, has been manufacturing ID cards for Estonia since 2001.

It is notable that this is the first tender in the last 15 years, where PPA decided to make participation in tender available to wider range of companies. Previous contract extensions with Trub AG were justified by “potential security risk avoidance reasons”.

Update: Gemalto and Safran Morpho appealed in court the results of the tender.
