I googled for "verify installed packages +debian" and it came up with
with this package "debsums":
"debsums can verify the integrity of installed package files against
MD5 checksums installed by the package, or generated from a .deb archive."

Do an "apt-cache show debsums" to see if it's exactely what you are
looking for

Also, check the debian reference guide. (slowly turning into the debian
bible :-)

======================= snip ======================
6.3.14 Verify installed package files
debsums enables verification of installed package files against MD5
checksums.
Some packages do not have available MD5 checksums. A possible temporary
fix for sysadmins:
# cat >>/etc/apt/apt.conf.d/90debsums
DPkg::Post-Install-Pkgs {"xargs /usr/bin/debsums -sg";};
