The rights of an individual to access personal information will be at the centre of new legislation on information and tracing.
Minister for Children Roderic O'Gorman said the bill that the Government is bringing forward will take a different approach using General Data Protection Regulation (GDPR) rules.
Speaking on RTÉ's Morning Ireland, Mr O'Gorman said that he plans to bring forward the new bill in the coming weeks to provide information for people who were subject to illegal birth registrations, people who were boarded out, and to adoptees.
He said he intends to use GDPR legislation to ensure that access to birth certificates and wider early birth information is central to the tracing legislation.
The minister acknowledged that even in the context of GDPR there are mechanisms whereby various rights are looked at in conjunction with each other, but said "the difference here is that the right to personal information will be central to the new legislation".
Minister O'Gorman said that his department is also working to help 151 individuals identified in the files of the St Patrick's Guild Adoption Society, who had illegally registered births, with issues of succession and the rectification of identity documents.
The minister said that in parallel with the new legislation the Government has tasked Dr Conor O'Mahony, the Special Rapporteur on Child Protection, to examine the next steps the Government can take in looking at the sampling review of historic files from adoption agencies.
He said the review found there were significant issues and "deeply disturbing practices" in terms of how births were registered in Ireland over decades and there is widespread public concern about that.
Dr O'Mahony has been asked to provide insight to the Government about the next steps to deal with illegal birth registrations.

Meanwhile, Minister O'Gorman has told the Dáil that Government will not oppose the second reading of a Sinn Féin Bill that seeks to ensure that all adopted people over the age of 18 have a legal right to access their own birth certificate.
However, he said the Government does have some concerns around the particular legislative approach taken by Sinn Féin and Government legislation is likely to overtake the Sinn Féin Bill.
Minister O'Gorman said that he expects to have Heads of Bill, ready for pre-legislative scrutiny, in the coming weeks.
He said the Government's legislation will be more comprehensive and insisted that access to birth information is a priority for both himself and the Government as a whole.
The Sinn Féin Bill was brought forward by their Spokesperson on Children Kathleen Funchion.
Ms Funchion acknowledged that a "wider more comprehensive information and tracing bill does need to be put forward".
However, she asked that TDs back her party's bill, as she believes it would have an immediate effect for adopted people.
She added that she has heard many stories about adoptees being pushed to the point of being emotional wrecks, even when they are seeking "simple information about themselves".
"So many adopted people have been denied this basic right for far too long. Everyone has the right to know who they are, where they were born, they have the right to know what name they were given at birth and they have the right to know on what date they were born and at what time. And they have a right to know their birth parent's names", she told the Dáil.
Holly Cairns, of the Social Democrats, accused Mr O'Gorman of playing politics with the Sinn Féin Bill by not opposing it.
She said that to "cynically not vote it down but then do nothing about it just adds further insult to injury, I think it's completely unnecessary particularly in relation to issues like this".
Mr O'Gorman said he had spoken to some 20 mother-and-baby home survivors yesterday, who had been adopted and raised by families in the United States and United Kingdom. He said that they explained the barriers that remain in place when it comes to seeking formation about themselves.
Labour TD Sean Sherlock told the Dáil that his party will be supporting the Sinn Féin Bill, however, he also told TDs that Labour has its own Bill which is making its way through the Seanad.
"I think that speaks volumes about the intent of the Houses of the Oireachtas to legislate for this issue. We would hope then that ultimately that there would be common ground found", he said.
Independent Catherine Connolly said that both she and fellow Independent Thomas Pringle also have a Bill, which will bring to four the number of Bills that will eventually be moving through the Oireachtas.
Richard Boyd-Barrett said that People-Before-Profit fully supported the Sinn Féin Bill. He told the Dáil that "I'm lucky in this regard, as an adoptee, that I didn't have to wade my way through all the barriers and difficulties that many adoptees have in order to secure access to their history and to their identity and to the basic facts of who they are".
He said that "in my case my mother actually came and found me. Although I can tell you she encountered extraordinary difficulties and shut doors and closed doors in a process completely mediated by the Church where they decided what information you did and didn't have".
He said he cannot imagine what it is like for people who come up against these barriers.
Mr Boyd-Barrett said that the need for more comprehensive legislation "should not be a block to progressing this particular measure".
Sinn Féin Leader Mary Lou McDonald called for a full public inquiry as a matter of urgency. She said that Kathleen Funchion's Bill was an important first step.
Ms Lou McDonald described the Government's decision not to oppose the bill, but also not to actively support it, as "cynical".
Yesterday, an independent review into adoption societies was published, which found no additional confirmed cases of illegal birth registrations.
The review was commissioned following the discovery of evidence of illegal birth registrations in the files of the St Patrick's Guild Adoption Society.
Since 2018, child and family agency Tusla and the Adoption Authority of Ireland (AAI) have examined 1,496 records from more than 30 agencies, under the oversight of an independent reviewer.
These agencies included adoption societies, nursing homes, and boarded out records.
The review found that neither the AAI or Tusla were able to identify "a unique marker" in the records sampled suggesting incorrect birth registration, similar to that found in the St Patrick's Guild files.
It identified potential markers or wording suggestive of markers across a percentage of the files it inspected.
Minister O'Gorman has established an Interdepartmental Group, which is currently examining issues arising for the individuals whose birth was the subject of an illegal birth registration in the St Patrick's Guild files.
The group is examining issues around inheritance, amending birth registrations, taxation, identity documents, which span the responsibility of a number of departments and offices.
It has been given two months to offer proposals.
