Blatter, re-elected for a fourth term in June which he says will be his last, also announced the creation of a new "good governance committee" featuring figures from outside FIFA, and three task forces.
The committee would include representatives of clubs, leagues, players, referees and women's football, among others.
However Blatter said that he had abandoned his idea of involving Henry Kissinger, the 88-year-old former U.S. Secretary of State, to act as an independent watchdog in one of FIFA's new committees
"I have to apologise because I did mention some big names at the Congress, but the former Secretary of State will not be in this governance committee, because we want to have someone who is active in politics now - a member of parliament or a minister, involved in the day-to-day work."
Blatter continued: "I think we have been rather ambitious in our road map, its a Formula One model, but we need to move forward.
"I feel very fulfilled, very happy that the executive committee is completely in step with what we want to achieve with the national associations.
"We are moving forward with a FIFA that, thanks to the good governance committee, which is a bit of a watchdog and will allow us in 2013, maybe even before, to present an image slightly better than the one we have currently.
"We want a fair image, which shows the will of the FIFA leadership to not dwell on the past, to face up to its problems and find solutions. Tackling problems isn't enough, we need to find solutions.
"When FIFA is attacked, the president is attacked and I have to defend the institution and myself, I hope this transparency will help us put our past concerns behind us."
Regarding the ISL case, he said: "This is an issue which has been raised by the national associations and members of FIFA, the executive committee of FIFA has decided that this case should be opened.
"We will give this file therefore to an independent organisation on the outside of FIFA so they can delve into this file and present them to us, that is all I can tell you on this famous ISL file," he said.
FIFA added in a statement: "However, this can only be done after a thorough legal analysis because of the complexity of the matter. The case will be opened at the next meeting of the executive committee in December 2011.
ISL went bankrupt in 2001. BBC's Panorama programme said last November that documents relating to a criminal investigation into the ISL collapse are believed to show that senior FIFA officials were paid kickbacks in return for granting ISL lucrative World Cup television and sponsorship rights during the 1990s.
"Transparency International was optimistic that FIFA would deliver on its promise to investigate the past and introduce reforms. This is a very important first step," said Sylvia Schenk, senior adviser for sport.
"But it is just the beginning. They have addressed several key issues but there is still a lot of work to do to restore credibility and we will have to wait until December to see how far and how quickly they act.
"It will be a big challenge to implement the reforms and it will require a change of culture in the whole world of football."
