The Basics of Judaism: Sin and Repentance: Confession:
What is the Jewish viewpoint on confessing one's sins?
Confession in the Torah is associated with bringing a sacrifice
to atone for a sin, but it does not depend on a sacrifice; it
applies in all places and at all times as part of the process of
repentance. The Kohen Gadol confessed publicly on Yom Kippur, but
ordinarily, confession is a private matter. For details see the
article on VIDUI in the Talmudic Encyclopedia, or the article on
"Confession of Sins" in the Encyclopedia Judaica.
