The author withdrew from the Jaipur Literature Festival in January after Islamic hardliners threatened to disrupt the gathering and police told him assassins from the Mumbai underworld were plotting to kill him.
The 64-year-old writer, who was born in Mumbai, spent a decade in hiding after Iranian spiritual leader Ayatollah Ruhollah Khomeini issued a fatwa in 1989 calling for his death over "The Satanic Verses".
According to the conference website, Rushdie's one-hour appearance on Friday will be titled "The Liberty Verses -- I am What I am and That's All That I am".
"I can confirm Mr. Rushdie will be attending in person," an event official told AFP on Tuesday, declining to give her name.
The Deoband seminary, a conservative Muslim university in north India that led the campaign against Rushdie's planned trip to Jaipur, said it was unaware of his new schedule but remained opposed to him visiting India.
"Salman Rushdie should never be allowed to step on Indian soil," seminary vice-chancellor Mufti Abul Qasim Nomani told AFP. "We did not allow him to participate in the festival and our stand is the same. He is anti-Islam."
After Rushdie was forced to abandon his Jaipur appearance, he vented his fury against radical Muslim activists and the Indian politicians who had failed to stand up to them.
"I will come to India many times, as I choose, to do what I will, and I will not allow these religious gangsters and their cronies in the government to prevent me," he said in a television interview from London.
Rushdie, who won the Booker prize for his 1981 novel "Midnight's Children", suggested police claims of an underworld plot may have been invented to prevent him attending the festival and to avoid antagonising radical Muslims.
He said he suspected the protests were connected to state elections in Uttar Pradesh, where about 18 percent of the population is Muslim. The elections have now been completed.
Rushdie, a keen Twitter user, has not yet posted about his planned arrival in India. In past years, he has spoken at both the India Today Conclave and the Jaipur festival without attracting protests.
Pakistan cricketer-turned-politician Imran Khan, Bollywood actress Kareena Kapoor and US former diplomat Henry Kissinger are also due to speak during the two-day event at the luxury Taj Palace hotel.
